Fabrication and characterization of alginate-zein core–shell microcapsules for controlled release of buckwheat honey

In this study, extrusion method was employed to fabricate alginate-zein core–shell microcapsules loaded with buckwheat honey by dropping alginate and buckwheat honey mixture solution into a 70.0 % zein ethanol solution(v/v) containing 5.0 % CaCl2 solution (wt%). The microcapsules were constructed by two parts: 1) the formation of hydrophilic beads through the crosslinking of alginate chains with Ca2+; 2) the introduction of alginate beads into the aqueous zein ethanol solution which decreased the ethanol concentration, prompting the precipitation of zein and the deposition of zein nanoparticles onto the surfaces of alginate beads. Comparing with the alginate beads, the prepared microcapsules not only possessed better water-holding capacity, but also achieved controlled release of buckwheat honey. Importantly, the microcapsules significantly retained the antioxidant activity of the buckwheat honey. Therefore, this innovative method for fabricating alginate-zein core–shell microcapsules can suggest a promising approach to broaden the application of buckwheat honey in the food field.

Silk fibroin-copper nanoparticles conglomerated polyurethane fibers incorporating calcium carbonate for enhanced fluid retention, antibacterial efficacy and promotion of cell growth

This work blended calcite crystals with polyurethane solution and fabricated into micro/nanofibers by electrospinning. Subsequently, these fibers were hydrothermally coated using silk fibroin and deposited with copper (Cu) nanoparticles (NPs). The morphology of fibers was smooth, and the diameter increased upon incorporation of CaCO3 from 1.56 ± 1.07 μm to 3.35 ± 0.8 μm. Adding SF and Cu increased the fiber diameter, and partial or complete masking of fibrous morphology occurred with higher concentrations. The contact angle declined from 105.3 ± 0.1° to 12.1 ± 0.1° in the scaffold with SF and Cu NPs, indicating hydrophilicity. The hydrothermally modified scaffolds showed multi-step decomposition temperature with improved thermal stability compared to pristine samples. The tensile strength of PU micro/nanofibers increased from 158.5 ± 0.5 MPa to 200.06 ± 0.2 MPa, and the enzymatic degradation of 46.6 ± 0.4% after 120 days was seen upon adding SF. The antibacterial activity of fibers against Escherichia coli (20.7 ± 0.16 mm) and Staphylococcus aureus (20.5 ± 0.4 mm) demonstrated significant antibacterial activity. The growth curve studies and biofilm inhibition tests from OD measurements showed self-inducing antibacterial activity from the hydrothermal deposition of Cu NPs. The 3T3 L1 and NIH 3T3 cells attached firmly and proliferated well on scaffolds with SF and Cu NPs. The measured cell viability was >300% and ≈200% in all composite scaffolds.

Simple and sensitive voltammetric sensor for in‐situ clinical and environmental 17‐β‐estradiol monitoring

AbstractThe direct electrochemical oxidation of 17‐β‐estradiol (E2) at conventional electrodes gives weak current signals making detection at trace levels difficult, as required for clinical and environmental applications. In order to strengthen the electrochemical behavior of E2, a simple and sensitive sensor has been realized based on a graphite screen printed electrode (GSPE) functionalized according to a two‐step procedure: i) drop‐casting deposition of gold nanoparticles (AuNPs); ii) electropolymerization of methylene blue (MB). The final PMB‐AuNPs‐GSPE platform was characterized by scanning electron microscopy (SEM), cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The pH value was optimized in order to obtain the best detection efficiency and the highest peak current response was obtained at pH 7.0. The synergistic contributions of both AuNPs and PMB allowed the proposed sensor to show a wide linear range from 0.5 to 125.0 μmol L−1 with a LOD of 41 nmol L−1, long‐term stability and good reproducibility (RSD=2.9 % for n=10). Moreover, the sensor was able to distinguish E2 from several interfering compounds commonly present in urine and river water as well as from other endocrine‐ disrupting chemicals (EDCs), denoting its high specificity to E2 molecule. Finally, the developed electrode platform was successfully applied to the determination of E2 in both human urine and river water samples without any purification step under the standard addition method.

Coupled carbon‑iron‑phosphorus cycling in the Rainbow hydrothermal vent field

Hydrothermal venting has been shown to play a role in the global biogeochemical cycles of three bio-essential elements: iron (Fe), carbon (C) and phosphorus (P). However, our insight into the coupled cycling of Fe and associated C and P in hydrothermal plumes as well as their long-term fate in the underlying sediments remains limited. We present a detailed study, tracing the biogeochemical pathways of hydrothermally sourced Fe and the associated C and P from a buoyant to a neutrally buoyant plume and to the underlying sediments. Combining chemical and micro(spectro)scopic methods, we characterize particulate and dissolved phases recovered from the water column and sediment at two sites: one located directly in the active Rainbow hydrothermal vent field at 36°N on the mid-Atlantic ridge (MAR) and one located 3 km NE of the active vents. Our results show that the precipitates in one of the largest hydrothermal plumes on the MAR consist of aggregates of Fe nanoparticles, comprising poorly-ordered Fe oxyhydroxides and polycrystalline Fe sulfides, coated with carbon that is likely of organic origin. The sediments underlying the hydrothermal plume show enrichments in organic C, Fe, P and vent-derived trace metals such as Cu that decrease with distance from active vents. The enrichment in organic C and persistence of apparently highly-reactive Fe phases after sediment burial may reflect enhanced preservation potential of both phases as a result of the formation of organic-mineral complexes. We further demonstrate that the scavenging of dissolved seawater phosphate (PO43−) by Fe nanoparticles is constrained to early stages of particle formation and sorption reactions in the buoyant hydrothermal plume and that P burial close to the vent field is driven by the deposition of the Fe nanoparticles. In the sediment, P is then efficiently retained through sink-switching from Fe-bound to more stable, authigenic apatite phases. As such, the sediments underlying the Rainbow vent seem to faithfully record coupled emission, scavenging and burial of essential elements and therefore offer potential for reconstruction of past venting activity. The deposition and burial of partly reduced plume material (e.g., Fe sulfides) in an oxic deep-sea sediment results in sediment chemistry and diagenesis that is very specific to the hydrothermal environment, while the redox signature of the plume is gradually lost. Beyond its role as a potential source of bioavailable Fe, we highlight how hydrothermal venting represents an efficient sink for organic C and bioavailable P. The findings contribute to understanding the profound impact of geological episodes of increased hydrothermal activity on ocean biogeochemistry and the coupled ocean-climate system.

Effective density of inhaled environmental and engineered nanoparticles and its impact on the lung deposition and dosimetry

BackgroundAirborne environmental and engineered nanoparticles (NPs) are inhaled and deposited in the respiratory system. The inhaled dose of such NPs and their deposition location in the lung determines their impact on health. When calculating NP deposition using particle inhalation models, a common approach is to use the bulk material density, ρb, rather than the effective density, ρeff. This neglects though the porous agglomerate structure of NPs and may result in a significant error of their lung-deposited dose and location.ResultsHere, the deposition of various environmental NPs (aircraft and diesel black carbon, wood smoke) and engineered NPs (silica, zirconia) in the respiratory system of humans and mice is calculated using the Multiple-Path Particle Dosimetry model accounting for their realistic structure and effective density. This is done by measuring the NP ρeff which was found to be up to one order of magnitude smaller than ρb. Accounting for the realistic ρeff of NPs reduces their deposited mass in the pulmonary region of the respiratory system up to a factor of two in both human and mouse models. Neglecting the ρeff of NPs does not alter significantly the distribution of the deposited mass fractions in the human or mouse respiratory tract that are obtained by normalizing the mass deposited at the head, tracheobronchial and pulmonary regions by the total deposited mass. Finally, the total deposited mass fraction derived this way is in excellent agreement with those measured in human studies for diesel black carbon.ConclusionsThe doses of inhaled NPs are overestimated by inhalation particle deposition models when the ρb is used instead of the real-world effective density which can vary significantly due to the porous agglomerate structure of NPs. So the use of realistic ρeff, which can be measured as described here, is essential to determine the lung deposition and dosimetry of inhaled NPs and their impact on public health.Graphical abstract

Anisotropic Magnetic Polymeric Particles with a Controllable Structure via Seeded Emulsion Polymerization.

Magnetic polymer composites have been widely utilized in potential applications in material science, such as reduction of dyes, immunodiagnostics, biomedicals, and magnetically controllable photonic crystals owing to large surface areas, fast separation, and recyclable performance. In this work, anisotropic magnetic particles were prepared by seeded emulsion polymerization, with morphologies of "Fe3O4-shell", "hemisphere-like", "raspberry-like", "multiple lobes-like", and "sandwich-like". Poly(styrene/divinylbenzene/mono-2-(methacryloxy)ethyl succinate)@ Fe3O4 (P(St/DVB/MMES)@Fe3O4) were the seed microspheres, and P(St/DVB/MMES)@Fe3O4@polymer particles are achieved by seeded emulsion polymerizations. The morphology of the particles depends on polymerization conditions (monomer ratios and surfactant), particle properties, and so on. Then, the minimum surface free energy change principles were used to predict the equilibrium morphologies of the magnetic polymer composites. Through theory, the model gives the correct tendency and good agreement with the equilibrium morphology which was in tandem with TEM results. Lastly, after in situ surface deposition of Ag nanoparticles, magnetic composite particles with sandwich-like morphology were applied for the catalytic degradation of 4-nitrophenol (4-NP) reacting with NaBH4. The apparent rate coefficient is 0.0069 s-1, and it can keep mainly about 80% efficiency in catalysis after five cycles.

Effect of Surface Wettability on Nanoparticle Deposition during Pool Boiling on Laser-Textured Copper Surfaces

Prior studies have evidenced the potential for enhancing boiling heat transfer through modifications of surface or fluid properties. The deployment of nanofluids in pool boiling systems is challenging due to the deposition of nanoparticles on structured surfaces, which may result in performance deterioration. This study addresses the use of TiO2–water nanofluids (mass concentrations of 0.001 wt.% and 0.1 wt.%) in pool boiling heat transfer and concurrent mitigation of nanoparticle deposition on superhydrophobic laser-textured copper surfaces. Samples, modified through nanosecond laser texturing, were subjected to boiling in an as-prepared superhydrophilic (SHPI) state and in a superhydrophobic state (SHPO) following hydrophobization with a self-assembled monolayer of fluorinated silane. The boiling performance assessment involved five consecutive boiling curve runs under saturated conditions at atmospheric pressure. Results on superhydrophilic surfaces reveal that the use of nanofluids always led to a deterioration of the heat transfer coefficient (up to 90%) compared to pure water due to high nanoparticle deposition. The latter was largely mitigated on superhydrophobic surfaces, yet their performance was still inferior to that of the same surface in water. On the other hand, CHF values of 1209 kW m−2 and 1462 kW m−2 were recorded at 0.1 wt.% concentration on both superhydrophobic and superhydrophilic surfaces, respectively, representing a slight enhancement of 16% and 27% compared to the results obtained on their counterparts investigated in water.

Investigation of biosensing properties in magnetron sputtered metallized UV-curable polymer microneedle electrodes

Direct management and assessment of metal film properties applied to polymer microneedle (MN) biosensors remains difficult due to constraints inherent to their morphology. By simplifying the three-dimensional structure of MNs and adjusting the deposition time, different thicknesses of Au films were deposited on the UV-cured polymer planar and MN substrates. Several properties relevant to the biosensing of the Au films grown on the polymer surfaces were investigated. The results demonstrate the successful deposition of pure and stable Au nanoparticles onto the surface of UV-curable polymer materials. Initially, Au islands formed within the first minute of deposition; however, as the sputtering time extended, these islands transformed into Au nanoparticle films and disappeared. The hydrophilicity of the surface remains unchanged, while the surface resistance of the thin film decreases with increasing thickness, and the adhesion to the substrate decreases as the thickness increases. In short, a sputtering time of 5–6 min results in Au films with a thickness of 100–200 nm, which exhibit exceptional comprehensive biosensing performance. Additionally, MNs made of Au/UV-curable polymers and produced using magnetron sputtering maintain their original shape, enhance their mechanical characteristics, and gain new functionalities. The Au/UV-curable polymer MNs exhibited remarkable electrode performance despite being soaked in a 37 °C PBS solution for 14 days. These discoveries have important implications in terms of decreasing the dependence on valuable metals in MN biosensors, lowering production expenses, and providing guidance for the choice and design of materials for UV-curable polymer MN metallization films.

Structure and properties of ZnO‐organobentonite‐filled natural rubber composites

AbstractThis study involved the preparation of composites consisting of zinc oxide (ZnO) nanoparticles deposited within the structure of organophilic bentonite. These composites were subsequently utilized as fillers in natural rubber (NR). The organobentonites were initially prepared via a cation exchange reaction using alkylammonium ions with different chain lengths (C8N−C18N) and later deposited by ZnO nanoparticles. The identification of the ZnO‐organobentonites was conducted using various techniques, including powder X‐ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), UV‐Vis spectroscopy, etc. The findings demonstrate the successful deposition of ZnO nanoparticles within the organobentonite's structure. The basal space between the silicate layers increased with the increasing chain length of alkylammonium ions. When added to NR, the ZnO‐organoclays mutually acted as a cure activator and filler. As expected, the ZnO‐organoclay modified by octadecylammonium ions (C18N) showed the greatest reinforcement due to its highest capability to enlarge the basal space between the silicate layers.

Electroless Deposition of Palladium Nanoparticles on Graphdiyne Boosts Electrochemiluminescence.

Modulating the electronic structure of metal nanoparticles via metal-support interaction has attracted intense interest in the field of catalytic science. However, the roles of supporting substrates in regulating the catalytic properties of electrochemiluminescence (ECL) remain elusive. Here, we find that the use of graphdiyne (GDY) as the substrate for electroless deposition of Pd nanoparticles (Pd/GDY) produces the most pronounced anodic signal enhancement in luminol-dissolved oxygen (O2) ECL system as co-reactant accelerator over other carbon-based Pd composite nanomaterials. Pd/GDY exhibits electrocatalytic activity for the reduction of O2 through a four-electron pathway at approximately -0.059 V (vs Ag/AgCl) in neutral solution forming reactive oxygen species (ROS) as intermediates. The study shows that the interaction of Pd and GDY increases the amount and stability of ROS on the Pd/GDY electrode surface and promotes the reaction of ROS and luminol anion radical to generate excited luminol, which significantly boosts the luminol anodic ECL emission. Based on quenching of luminol ECL through the consumption of ROS by antioxidants, we develop a platform for the detection of intracellular antioxidants. This study provides an avenue for the development of efficient luminol ECL systems in neutral media and expands the biological application of ECL systems.

Antimicrobial behavior of nanocoated orthodontic micro-implants: An in vitro study.

The need to overcome the failure of orthodontic micro-implants which might reach to 30% has led to the development of different methods, one of which is nanoparticle deposition. To evaluate the anti-microbial efficiency of TiO2 and ZnO nanoparticles (NP) when used as a coating for orthodontic micro-implants. Thirty titanium alloy micro-implants were used in the presented study. They were divided into three groups according to the coating method and the coating materials used: the control group without surface coating; the titanium dioxide (TiO2)-coated group, in which direct current (DC) spattering was used to coat the micro-implants with a TiO2 layer; and the TiO2 and zinc oxide (TiO2ZnO)-coated group, in which the micro-implants were coated with a TiO2 layer via direct current (DC) spattering and a zinc oxide (ZnO) layer via laser vacuum. The micro-implant surfaces were characterized using scanning electron microscopy (SEM) and an energy-dispersive spectrometer (EDS). The antibacterial susceptibility was assessed using gram-positive and gram-negative bacteria. SEM and EDS tests confirmed the coating of the micro-implants in the TiO2- and TiO2ZnO-coated groups. The micro-implants in the TiO2- and TiO2ZnO-coated groups demonstrated higher antibacterial ability than the control group. This study demonstrated the significance of improving the surface of orthodontic micro-implants by coating them with TiO2 and ZnO nanoparticles to improve osseointegration and prevent biofilm formation.

Surface structuring and in situ synthesis of nanoparticles by ultrashort laser processing on hydroxyapatite

Ultrashort laser pulses represent a versatile tool that finds application in a variety of fields allowing precise and controlled modification of any kind of materials. The material surface modification, by inducing the formation of micro and nanostructures or providing chemical changes, or its functionalization with other materials, in form of nanoparticles, strongly affects the behavior and performances of such materials. The surface structuring and the synthesis and deposition of metallic nanoparticles has both been obtained by laser exposure. The two processes are performed consecutively, on hydroxyapatite sample surface. The synthesis of silver nanoparticles (AgNPs) takes place on the sample surface, while immersed in a solution of silver nitrate (AgNO3), by laser-induced multiphoton photoreduction of silver ions (Ag+).

Electrophoretic Deposition of Single Nanoparticles.

The controlled assembly of colloid particles on a solid substrate has always been a major challenge in colloid and surface science. Here we provide an overview of electrophoretic deposition (EPD) of single charge-stabilized nanoparticles. We demonstrate that surface templated EPD (STEPD) assembly, which combines EPD with top-down nanofabrication, allows a wide range of nanoparticles to be built up into arbitrary structures with high speed, scalability, and excellent fidelity. We will also discuss some of the current colloid chemical limitations and challenges in STEPD assembly for sub-10 nm nanoparticles and for the fabrication of densely packed single particle arrays.

Assessing the effect of Fe2O3 nanoparticle addition on microalgae wastewater treatment and biomass composition

The addition of Fe2O3 nanoparticles to microalgae cultures has gained popularity since it has been demonstrated to enhance microalgae growth and metabolite accumulation. However, most of the literature has been focused on small batch laboratory-scale studies under controlled conditions and the need of continuous studies under real environmental conditions is needed to demonstrate the feasibility of this process. In this study, the effect of Fe2O3 nanoparticles on the metabolism and nutrient uptake of a microalgae-cyanobacteria consortium cultivated in wastewater was elucidated. Different concentrations of Fe2O3 nanoparticles (10, 20, 30 and 70 mg L−1) were assessed at least for 21 days in outdoor cylindrical PBRs at 7 days of hydraulic retention time. No significant difference in microalgae growth, microalgae biomass composition and nutrient uptake was observed at concentrations <30 mg L−1. Moreover, when 30 mg L−1 were added to the culture, the carbohydrate content increased up to 38 % but a decrement in biomass concentration of 18 % was observed by the deposition of nanoparticles on the cyanobacteria cell wall. The addition of 70 mg Fe2O3 L−1 reduced the content of carbohydrate and biomass concentration but did not influence the nutrient uptake from wastewater. In brief, Fe2O3 NP supplementation at 30 mg L−1 can be added as a strategy to stimulate carbohydrate content during microalgae-based wastewater treatment.

Leveraging novel innovative thermoresponsive polymers in microneedles for targeted intradermal deposition

Microneedles have garnered considerable attention over the years as a versatile pharmaceutical platform that could be leveraged to deliver drugs into and across the skin. In the current work, poly (N-isopropylacrylamide) (PNIPAm) is synthesized and characterized as a novel material for the development of a physiologically responsive microneedle-based drug delivery system. Typically, this polymer transitions reversibly between a swell state at lower temperatures and a more hydrophobic state at higher temperatures, enabling precise drug release. This study demonstrates that dissolving microneedles patches made from PNIPAm, incorporating BIS-PNIPAm, a crosslinked polymer variant, exhibit enhanced mechanical properties, evident from a smaller height reduction in microneedle (∼10 %). Although microneedles using PNIPAm alone were achievable, it displayed poor mechanical strength, requiring the inclusion of additional polymeric excipients like PVA to enhance mechanical properties. In addition, the incorporation of a thermoresponsive polymer did not have a significant (p > 0.05) impact on the insertion properties of the needles as all formulations inserted to a similar depth of 500 µm into ex vivo skin. Furthering this, the needles were loaded with a model payload, 1,1′-dioctadecyl-3,3,3′,3′-tetramethylindodicarbocyanine perchlorate (DID) and the deposition of the cargo was monitored via multiphoton microscopy that showed that a deposit is formed at a depth of ≈200 µm. Also, it was revealed that crosslinked-PNIPAm (Bis-PNIPAm) formulations exhibited notable skin accumulationof the dye only after 4 h, independent of the excipient matrix used. This phenomenon was absent in non-crosslinked PNIPAm formulations, indicating a deposit formation in Bis-PNIPAm microneedle formulation. Collectively, this proof-of-concept study has advanced our understanding on the possibility to use PNIPAm for dissolving microneedle fabrication which could be harnessed for the deposition of nanoparticles into the dermis, for extended drug release within the skin.

Numerical simulation of unsteady magneto hydrodynamic flow of nanoparticle deposition in the porous alveolar ducts

This study aims to investigate a numerical model of dust particle deposition in the human lung. There were significant discrepancies in deposition inside each alveolate duct and between ducts of a given generation, indicating that the mean acinar concentration can be greatly exceeded by limited particle concentrations. During expiration, the huge particles try to exit the construction but are failed. The similarity transformation is used to describe the differential equations controlling the flow. The various systematic quantities, such as the fluid velocity, and dust particle velocity are determined. In this research, non-linear governing coupled partial differential equations are explained by developing a finite-difference method established on the Crank-Nicolson model that is accurate, precise, widely validated, and unconditionally stable. The technique’s precision and efficacy are proven. To show how various physical factors affect the velocity and temperature profiles, various numerical data are collected and visually displayed. For each of the characteristics tested, the results show that the nano particles’ velocity is higher in comparison to the fluid particles.

Engineering Triple‐Phase Boundary in Pt Catalyst Layers for Proton Exchange Membrane Fuel Cells

AbstractEngineering triple‐phase boundaries in low Pt‐loaded catalyst layers is highly desired yet challenging due to the poor Pt utilization caused by inhomogeneous Nafion ionomer coverage over catalyst nanoparticles and high mass transport resistance near catalyst surface. Herein, an effective Pt catalyst/support design strategy by using urea to modify the carbon supports is reported, in which the balance between nitrogen doping and Pt nanoparticle deposition can be well achieved without sacrificing catalyst performance. The nitrogen‐modified carbon with the positively charged surface can electrostatically attract with ionomer with negative charges in a catalyst ink. Meanwhile, ionomer can be preserved into a solid catalyst layer, forming a desirable ionomer/catalyst interface with improved dry proton accessibility and lowered oxygen transport resistance. Consequently, this interface leads to striking performance improvement in the kinetic and mass transport regions in the membrane electrode assembly level, with the current density of 1.11 A cm−2 at 0.65 V under 50% RH and 85 °C operating conditions, reaching 2.8 times this value compared with the one without modification.

Transport and retention of silica nanoparticles in glass-bead columns: effects of particle size, type, and concentration of ionic species

Silica nanoparticles (SiO2 NPs) have garnered substantial attention as versatile additives in saline fluids, finding application in areas like environmental remediation, wastewater treatment, enhanced oil recovery, and carbon geo-sequestration. Despite their potential, the intricate interaction between electrolyzed nanoparticles and porous media remains inadequately researched in these contexts. This study delves into the pivotal yet underexplored aspect of silica nanoparticle absorption behavior within porous media, a key determinant of their practical effectiveness. The research focuses on silica particles with dimensions of 10 nm and 50 nm, synthesized via hydrolysis and condensation of tetraethyl orthosilicate (TEOS) in methanol. Employing packed glass bead columns as a surrogate for porous media, the study unravels the complex mechanisms governing nanoparticle transport and deposition. Comprehensive investigations encompass variations in particle sizes, ionic strength, and ionic species, resulting in the examination of 48 distinct flooding scenarios. UV/Vis spectrophotometry is used to quantify nanoparticle concentrations in effluents, elucidating their transport behavior within the porous media. Concurrently, pressure drop alterations across the media serve as indicators of particle plugging and changes in permeability. Intriguingly, specific conditions involving a nanofluid comprising 50 nm silica nanoparticles and 10,000 ppm of magnesium chloride exhibit pronounced permeability reduction, offering potential insights for optimizing applications. Particularly noteworthy is the unique reduction in silica particle retention on glass bead surfaces as salinity increases, especially in the presence of magnesium sulfate. A concentration of 5000 ppm magnesium sulfate induces a log-jamming mechanism, resulting in an amplified final-to-intermediate permeability ratio. Experimental outcomes align with observations from scanning electron microscopy, improving understanding of porous media retention mechanisms. This study contributes to a deeper understanding of interactions between nanoparticles and porous media, paving the way for enhanced application strategies.
