Silk Foams with Metallic Nanoparticles as Scaffolds for Soft Tissue Regeneration

Tissue regeneration can be achieved by providing endogenous cells with a biomaterial scaffold that supports their adhesion and proliferation, as well as the synthesis and deposition of an extracellular matrix (ECM). In this work, silk fibroin protein foams were formed by lyophilization to generate tissue engineering scaffolds. Three types of medically relevant nanoparticles (NPs) (iron oxide, gold and silver) were added to this biomaterial to assess the ability of silk foams to be functionalized with these NPs. The structural and mechanical properties of the foams with and without the NPs were suitable for tissue support. The in vitro cytocompatibility of the scaffolds was confirmed according to the ISO 10993 guidelines. The biocompatibility of the scaffolds was investigated by assessing inflammation and endogenous cell colonization in a mouse subcutaneous model These in vivo experiments demonstrated a loss of acute inflammation and the absence of chronic inflammation in the grafted animals. The obtained results show that silk foams are good candidates for supporting soft tissue regeneration with the additional possibility of functionalization with NPs.

Biosynthesis; Characterization; and Antibacterial, Antioxidant, and Docking Potentials of Doped Silver Nanoparticles Synthesized from Pine Needle Leaf Extract

The current study focused on the synthesis of doped silver nanoparticles (doped AgNPs) with yttrium (Y), gadolinium (Gd), and chromium (Cr) from pine needle leaf extract (PNLE). X-ray diffraction (XRD) was performed to assess the phase formation, detecting 61.83% from Ag and 38.17% for secondary phases of AgCl, AgO, Y, Cr-, and Gd phases. The size and shape of the NPs were determined by transmission electron microscopy (TEM), showing a spherical shape with an average particle size of 26.43 nm. X-ray photoelectron spectroscopy (XPS) detected the oxidation state of the presented elements. The scanning electron microscope (SEM) and the energy-dispersive X-ray analysis (EDX) determined the morphology and elemental composition of the NPs, respectively. Fourier transform infrared spectroscopy (FTIR) determined the different functional groups indicating the presence of Ag, Y, Gd, Cr, and other groups. Photoluminescence (PL) spectroscopy showed the optical properties of the NPs. A vibrating sample magnetometer (VSM) revealed the ferromagnetic behavior of the doped AgNPs. The antibacterial activity of the doped AgNPs was tested against six uro-pathogenic bacteria (Staphylococcus aureus, Staphylococcus haemolyticus, Enterococcus faecalis, Escherichia coli, Klebsiella pneumonia, and Pseudomonas aeruginosa) using the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) microdilution assays, agar well diffusion assay, time–kill test, and antibiofilm screening assays, revealing significant activity, with MICs ranging between 0.0625 and 0.5 mg/mL and antibiofilm activity between 40 and 85%. The antioxidant activity was determined by the 1,1, diphenyl 1-2 picrylhydrazyl (DPPH) radical scavenging assay with a potential of 61.3%. The docking studies showed that the doped AgNPs had the potential to predict the inhibition of crucial enzymes such as penicillin-binding proteins, LasR-binding proteins, carbapenemase, DNA gyrase, and dihydropteroate synthase. The results suggest that the doped AgNPs can be applied in different medical domains.

A double-edged sword effect of silver nanoparticles on angiogenesis in 4T1 breast cancer-bearing mice.

Silver nanoparticles (AgNPs) are increasingly known to have anticancer effects, but few studies have examined their adverse effects, so the underlying mechanisms are not yet fully understood. The current study investigated the critical influence of AgNPs on angiogenesis in 4T1 breast cancer-bearing mice. The sub-lethal dose of AgNPs (0.25mg/kg) was carried out. Female BALB/c mice (N = 35) were divided into 7 groups; normal control, cancer control, AgNPs control (one dose of (0.25mg/kg) AgNPs), single dose AgNPs before cancer, single dose AgNPs after cancer, 5 doses AgNPs after cancer, and doxorubicin. 4T1 breast cancer cell induction was performed subcutaneously on the left flank. Intraperitoneal (IP) administration of AgNPs and doxorubicin was carried out for all studied groups. Weight gain was normal in all study groups except the doxorubicin-treated group. Administering AgNPs before cancer induction promotes tumorigenesis, raises MMP-2 and MMP-9 activity, and increases CD31 and Ki67 expression. The cancer control group experienced the same outcomes. On the other hand, depending on the administered doses, the injection of AgNPs after tumor induction resulted in a notable decrease in tumor volume.In the doxorubicin-treated group, similar results were observed, while a dose of AgNPs‌ before cancer induction lead to increasing tumor volume compared to the cancer control group. The differences of biochemical markers including LDH, ALP, AST, ALT, BUN, and Cr between different groups were not significant. Significant differences were seen among all studied groups except doxorubicin and single dose AgNPs before cancer groups for serum TAC levels. It appears that AgNPs are considered a double-edged sword in the fight against cancer. AgNPs not only have anti-cancer effects on tumor size and angiogenesis, but they also might have cancer-stimulating roles. To confirm this conclusion, more detailed investigations are needed.

Effect of silver nanoparticles in polyethylene packaging on physicochemical, microbiological, and textural properties of oil cake.

This study investigated silver nanoparticle (SNP)/titanium dioxide polyethylene films as chemical preservative substitutes to increase the shelf life of oil cake. The research examined three types of packaging films: standard low-density polyethylene (LDPE), LDPE with 3% SNP, and LDPE with 5% SNP, and assessed their impact on oil cake shelf life. Analysis of packaging films included scanning and transmission electron microscopy (SEM and TEM), and Fourier-transform infrared spectroscopy. The study evaluated the effects of SNP on chemical and microbial stability on oil cakes in different storage days (1st, 15th, 30th, and 37th days) at 25 °C. Parameters such as moisture content, water vapor permeability, water activity, peroxide, fat acidity, texture, and microorganisms were studied. The results demonstrated that SNP-containing films can extend the shelf life of oil cake up to 37 days, marked by a significant decrease in microbial growth, particularly mold, compared to conventional packaging films. Notably, films with 5% SNP concentrations exhibited the highest efficacy in preserving the quality of the oil cake. Higher concentrations of SNP led to an increased reduction in microbial load and enhanced mold control while maintaining favorable quality assessment indices throughout the storage period from day 1 to day 30. Remarkably, oil cake packaged with a 5% SNP polymer film displayed the most promising outcomes, extending shelf life up to 30 days at 25 °C.

Biogenic synthesis of silver nanoparticles from Hylocereus undatus peel waste: exploring EGFR inhibition for targeted therapy of cervical and breast carcinomas

Abstract Background Cancer is one of the leading causes of death worldwide, with breast and cervical cancers being the most common among women. Over 100,000 new cases of breast cancer and 510,000 new cases of cervical cancer are diagnosed annually. This study aimed to develop and evaluate an eco-friendly, low-cost method to synthesize silver nanoparticles using Hylocereus undatus (dragon fruit) peel extract for their anticancer activity. Results Silver nanoparticles loaded with Hylocereus undatus fruit peel extract were successfully developed by a green synthesis technique and were optimized by UV–vis spectroscopy. The nanoparticles had an average size of 71.66 nm, a polydispersity index of 0.3754, and a zeta potential of − 38.52, with a spherical shape and 79.5% silver content. Their maximum absorbance was at 448 nm. Further, in vitro anticancer activity via MTT (3-(4, 5-dimethylthiazolyl-2)-2, 5-diphenyltetrazolium bromide) assay was evaluated and the synthesized nanoparticles displayed IC50 values at 23.51 µg/ml and 23.66 µg/ml against Hela and MDA MB 231 cell lines, respectively. Cytocompatibility studies showed high cell viability (≥ 95%) in L929 mouse fibroblast cells, indicating low toxicity. In silico analyses, including network pharmacology and molecular docking, identified kaempferol and quercetin as key anticancer compounds, with epidermal growth factor receptor (EGFR) (PDB ID: IM17) being the most significant protein target. Docking studies performed by using the Glide module of Schrodinger’s software displayed that kaempferol and quercetin had higher binding affinities for EGFR as compared to the standard drug erlotinib, with MET 769 being a crucial binding site. Conclusion Thus, the outcomes suggest that synthesized silver nanoparticles loaded with Hylocereus undatus fruit peel extract could be a potential and promising drug carrier aiding in cancer treatment.

Beet Root Peel Extract as a Natural Cost‐Effective pH Indicator and Food Preservative in Edible Film: Shelf Life Improvement of Cold‐Stored Trout Fillet

ABSTRACTIn this study, chitosan (C)‐polyvinyl alcohol (P) edible film containing bio‐fabricated nanosilver particles (nAg) (as antimicrobial agent) and beetroot peel extract (BRPE) (as antioxidant agent and pH indicator) was used as spoilage indicator in cold‐stored rainbow trout fillets. DPPH (2,2‐diphenyl‐1‐picrylhydrazyl) radical scavenging activity (43.02%), reducing power (2.87), and total phenolic content (360.50 mg GAE/g) of ethanolic BRPE were higher than aqueous extract. Silver nanoparticles were biosynthesized using silver nitrate reduction by chitosan, confirmed by UV–Visible spectroscopy, optical and scanning electron microscope images, and X‐ray diffraction analysis. The highest tensile strength (4.20 MPa) and elongation at break (118%) belonged to the CP‐BRPE film, and the lowest water vapor permeability (2.45 10−5 g/s/m/P) was related to the CP‐nAg film. Also, the lowest total viable count (6.17 log CFU/g), psychrotrophic bacteria (6.27 log CFU/g), Enterobacteriaceae (4.9 log CFU/g), pH (5.66), total volatile basic‐nitrogen (TVB‐N) (22.1 mg/100 g of fish), and thiobarbituric acid reactive substances (TBARS) (0.705 mg MDA/kg of fish) values of the packaged trout fillets were significantly (p ≤ 0.05) observed in CP‐BRPE‐gnAg treatment among the other treatments at the end of the storage period, and CP‐gnAg, CP‐BRPE, and CP treatments were in the next ranks, respectively. Colorimetric analysis of the used films showed that the films containing BRPE depicted color spectra of red to yellow at the same time as the spoilage symptoms initiated in the packaged fillets. It is concluded that BRPE not only increased the preservative effects of chitosan‐polyvinyl alcohol film containing green silver nanoparticles but also can be considered as a natural cost‐effective spoilage indicator of the rainbow trout fillets during cold storage time.

Mycosynthesis of silver nanoparticles from endophytic Aspergillus parasiticus and their antibacterial activity against methicillin-resistant Staphylococcus aureus in vitro and in vivo

BackgroundMethicillin-resistant Staphylococcus aureus (MRSA) is a drug-resistant and biofilm-forming pathogenic bacteria with severe morbidity and mortality. MRSA showed resistance against currently available antibiotics. Thus, there is an urgent need to develop novel effective treatments with minimal side effects to eliminate MRSA.AimIn this study, we aimed to mycosynthesize silver nanoparticles (AgNPs) using the endophytic fungus Aspergillus parasiticus isolated from leaves of Reseda Arabica and to examine their antibacterial activity against MRSA.ResultsScreening of fungal secondary metabolites using gas chromatography–mass spectroscopy (GC–MS) analysis revealed the presence of high content of bioactive compounds with antibacterial activities. AP-AgNPs were mycosynthesized for the first time using ethyl acetate extract of A. parasiticus and characterized by imaging (transmission electron microscopy (TEM), UV–Vis spectroscopy, zeta potential, X-ray diffraction (XRD), energy-dispersive X-ray analysis (EDX), and Fourier transform infrared spectroscopy (FTIR)). The agar well diffusion method revealed the antibacterial activity of AP-AgNPs against MRSA with 25 μg/mL of minimum inhibitory concentration (MIC). AP-AgNPs were shown to exert antibacterial action via a bactericidal mechanism based on flow cytometry, scanning electron microscopy, and transmission electron microscopy assessment. Our data demonstrated the effective interaction of AP-AgNPs with the bacterial cell membrane, which resulted in cell membrane damage and disruption of cell surface structure. Furthermore, AP-AgNPs successfully prevented the development of MRSA biofilms by disturbing cell adhesion and destructing mature biofilm reaching over 80% clearance rate. Interestingly, topical application of AP-AgNPs to superficial skin infection induced by MRSA in mice effectively promoted wound healing and suppressed bacterial burden.ConclusionOur results provide a novel green nanoparticle drug design with effective therapeutic potential against MRSA-induced skin infection.

Mechanisms of ROS-induced mitochondria-dependent apoptosis in Phaeodactylum tricornutum under AgNPs exposure

IntroductionNanomaterials such as silver nanoparticles (AgNPs) have gained widespread application across various fields. However, the large-scale production and application of AgNPs have raised concerns about their distribution in the environment and potential pollution issues.MethodsThis study investigates the toxic effects of AgNPs on the diatom Phaeodactylum tricornutum by employing electron microscopy for cellular observation, quantifying apoptotic cell numbers, and measuring antioxidant indicators. The research examines how varying concentrations of AgNPs induce stress in P. tricornutum and the specific mechanisms of the toxic effect.ResultsThe findings reveal that AgNPs induce apoptosis in P. tricornutum cells by triggering a mitochondria-mediated pathway, marked by a decrease in mitochondrial membrane potential and the activation of caspase enzymes. Additionally, AgNP exposure results in an overproduction of reactive oxygen species (ROS) within the algal cells, leading to lipid peroxidation of the cell membrane and a consequent increase in malondialdehyde (MDA) levels. This oxidative stress response induces the upregulation of antioxidant enzyme activities in an attempt to mitigate the excessive ROS.DiscussionROS is identified as the primary factor responsible for inducing mitochondria-mediated apoptosis. The research results will provide a theoretical basis for understanding the toxic effects and mechanisms of AgNPs on marine microalgae.

The impact of varying sizes of silver nanoparticles on the induction of cellular damage in Klebsiella pneumoniae involving diverse mechanisms

Abstract Silver nanoparticles (AgNPs) are extensively studied as potent antibacterial agents targeting antibiotic-resistant pathogens. Cellular damage induced through various mechanisms that can affect multiple cell components like the outer membrane, enzymes, and proteins is closely linked to their chemical and morphological characteristics. We investigated the impact of AgNPs’ size on their antibacterial effectiveness using two differently sized nanoparticles: silver nanoparticle-Citrus limon (AgCL) with an average size of 21 nm and silver nanoparticle-Citrus sinensis (AgCS) with an average size of 13 nm, derived from C. limon and C. sinensis through environmentally friendly methods. The study evaluated their antibacterial effects by assessing morphology changes via scanning electron microscopy, metabolic alterations using Fourier transform infrared (FT-IR) spectroscopy, and oxidative stress responses through biochemical markers in Klebsiella pneumoniae cells exposed to AgNPs. The results showed that both AgCL and AgCS exhibited remarkable antibacterial activity, evidenced by inhibition zones of 14 ± 1.5 and 16 ± 1.0 mm, respectively. Morphological changes in K. pneumoniae cells treated with AgNPs were size dependent, with notable alterations noted. FT-IR spectroscopy revealed size and concentration-dependent biochemical changes, particularly in shifts in functional groups involved in the fluidity of cell wall lipid, and protein structure. Exposure to AgNPs led to increased oxidative stress markers like lipid peroxides and reduced levels of enzymatic and non-enzymatic antioxidants, more prominently observed with smaller AgCS nanoparticles (13 nm). AgNPs induce oxidative stress and morphological changes in K. pneumoniae strains, with smaller nanoparticles demonstrating greater efficacy. These findings underscore the importance of nanoparticle size in optimizing the antibacterial properties against pathogens.

Performing hardness classification using diffusive memristor based artificial neurons

Abstract Artificial neurons and synapses are the building blocks for constructing a neuromorphic system such as Spiking Neural Network (SNN) or Artificial Neural Network (ANN). Recently, there has been tremendous interest in using memristors to develop neuromorphic technologies that can be used in advanced SNNs and ANNs. Memristors, because of their simple device structure, easy and high-density fabrication, and integration with other semiconductor electronics are suitable candidates for the construction of neuromorphic concepts. However, not much has been discussed about using memristors for the development of sensors that can be utilized for object- classification especially their rigidity, shape and structure. In this article, we propose the application of memristors, specifically silver nanoparticle based diffusive memristor, in conjunction with a piezoelectric sensor within a robotics gripper, serving as one receptor (a tactile sensor) that triggers neuron circuitry with memristors to generate spikes. Furthermore, to perform hardness classification, we utilized various objects to collect data and generated multiple spikes corresponding to each object. This data was then utilized with a machine learning algorithm. The outcomes were compared with the accuracy of commercial FSR tactile sensors. Our approach demonstrated the capability of diffusive memristors in generating neuron spikes from tactile stimuli for hardness classification, achieving accuracy ranging from 82% to 100% during the validation of 20% test data across various algorithms, while the FSR sensors achieved an accuracy range of 95% to 98%.&amp;#xD;

Lemongrass-Synthesized Silver Nanoparticles as Preservatives of Fermented Locust Beans

Fermented locust beans (FLB), produced from Parkia biglobosa (Mimosaceae-Fabaceae), are used in many parts of West Africa, including Nigeria, as condiments to enhance the taste and nutritional quality of foods. These benefits are, however, marred by the short shelf-life of FLB. Traditional preservative methods and the use of chemicals have their shortcomings. This study, therefore, investigated the effectiveness of lemongrass-synthesized silver nanoparticles (LSSNP) as a preservative of FLB. The LSSNP was prepared, characterized, and used to treat fresh FLB at 10% v/w. Dynamic light scattering analysis revealed a mean hydrodynamic size of 89 nm for the LSSNP, while transmission electron micrograph showed roughly spherical particles with an average size of 100 nm. Bacillus licheniformis KGEB16, B. licheniformis APBSWPTB167, B. licheniformis PS4, B. subtilis CICC10148, and Enterobacter xiangfangensis M5S2B6 isolated were susceptible to LSSNP with comparable zones of inhibition to reference antibiotics. A significant reduction of the microbial load of FLB by up to 63.7% due to LSSNP treatment was achieved. The organoleptic and proximate properties of LSSNP-treated FLB were preserved. A histo-morphological study showed normal hepatic architecture in rats fed with LSSNP-treated FLB. This study showed that LSSNP possesses antimicrobial properties and can be employed as a green and safe alternative for the preservationof FLB.

Bio-inspired one-pot synthesis of luminescent silver nanoparticles and its significant utility as a fluorescence nano sensor for analysis of two adjunctive COVID-19 drugs.

This study reveals one-step green synthesis of plant inspired silver nanoparticles (Ag-NPs). The synthesis procedure relies on the bio-reduction of Ag+ to Ag0 using orange waste (orange peel) extract as cheap, readily available, sustainable, biocompatible feedstocks as a reducing and stabilizing agent. The prepared Ag-NPs passed through a full characterization procedure for better confirmation and elucidation of optical and structural properties. The fluorescence of the prepared Ag-NPs has a quantum yield of 17.15% enabling its potential use in chemical sensing of drugs. Ag-NPs are conceived to be used as a fluorescent nano sensor for sensitive, ecofriendly, rapid spectrofluorimetric determination of two recent direct oral anticoagulants, namely, rivaroxaban (RIV) and edoxaban tosylate monohydrate (EDT); COVID-19 adjunctive drugs in their raw materials and pharmaceutical tablets. The fluorescence of the prepared Ag-NPs at 333nm was found to be substantially quenched in existence of increasing concentrations of each drug. The quenching mechanisms were studied and explained. The validation of the method revealed linear correlation over the ranges of 0.5-10µg/ml with an excellent regression correlation (r=0.9999) for both drugs with minimum detection limits of 0.14 and 0.16µg/ml for rivaroxaban and edoxaban tosylate monohydrate, correspondingly. Three different metrics were employed for verifying the greenness profile of the presented study. The findings of the greenness assessment were congruent and compatible with the green synthesis procedure, ecofriendly analysis, and the exclusion of using organic solvents and noxious materials opening an avenue for green synthesis of nanoparticles instead of chemical and physical methods.

Rapid Dynamic Surface-Enhanced Raman Spectroscopy Detection of Amoxicillin-Mediated Morphological Changes in a Pathogen for Diagnosis of Clinical Urine Samples.

The swift and stable detection of pathogens in urine samples holds significant implications for the immediate clinical diagnosis and treatment of urinary tract infections (UTIs). In this study, we propose a detection strategy utilizing a hybrid substrate composed of graphene oxide (GO) and silver nanoparticles (Ag NPs) for the detection of pathogens subjected to amoxicillin-mediated (amo-mediated) treatment. This strategy employs dynamic surface-enhanced Raman spectroscopy (D-SERS) for stable and rapid detection, capturing signal variations induced by amo-mediated changes in pathogen morphology. During the 5 min D-SERS detection time window, stable SERS signals were detected for three types of pathogens and four types of pathogens were successfully distinguished using principal component analysis (PCA). In comparison to conventional nanosubstrates, the GO/Ag NP hybrid substrate exhibits outstanding stability and enhancement effects. This approach enables the dual detection of the pathogen cell structure and metabolites, facilitating specific identification of pathogens in the urinary tract, with a detection limit for Escherichia coli reaching 1 × 104 colony-forming units (CFU)/mL, meeting the clinical microbiology laboratory diagnostic standards for UTIs (105 CFU/mL). Testing of 188 clinically collected urine samples using this strategy yielded a sensitivity (SENS) of 86.4% and a specificity (SPC) of 89.7%. This introduces a novel method for diagnosing UTIs, offering broad applications in the field of clinical pathogen detection.

Uncertainty analysis of MHD oscillatory flow of ternary nanofluids through a diverging channel: a comparative study of nanofluid composites

Purpose This study aims to investigate the heat and mass transfer characteristics of a temperature-sensitive ternary nanofluid in a porous medium with magnetic field and the Soret–Dufour effect through a tapered asymmetric channel. The ternary nanofluid consists of Boron Nitride Nanotubes (BNNT), silver (Ag) and copper (Cu) nanoparticles, with a focus on understanding the thermal behaviour and performance across mono, hybrid and tri-hybrid nanofluids. This paper also examines the thermal behaviour of MHD oscillatory nanofluid flow and carries out an uncertainty analysis of the model using the Taguchi method. Design/methodology/approach The governing equations for this system are transformed into coupled linear partial differential equations using non-similarity transformations and solved numerically with the Crank–Nicolson scheme. The impact of temperature sensitivity at three distinct temperatures (5°C, 20°C and 60°C) is incorporated to analyse variations in viscosity and Prandtl number. The study also examines the combined effects of Soret–Dufour numbers and thermal radiation on heat and mass transfer within the nanofluid. Findings The results demonstrate that the inclusion of BNNT, Ag and Cu nanoparticles significantly enhances heat and mass transfer rate, with copper nanoparticles showing superior performance in terms of skin friction and heat transfer rates. The Soret and Dufour effects play critical roles in modulating heat and mass diffusion within tri-hybrid nanofluids. The study reveals that temperature sensitivity alters heat and mass transfer characteristics depending on the temperature range, with pronounced variations at elevated temperatures. The influence of thermal radiation and the Peclet number is found to significantly impact temperature distribution and overall heat transfer performance within the asymmetric channel. Originality/value To the best of the authors’ knowledge, this study is the first to analyse the heat and mass diffusion in a ternary nanofluid composed of BNNT, Ag and Cu nanoparticles, considering porous media, oscillatory flow and thermal radiation within a tapered asymmetric channel. The research extends to a novel examination of temperature sensitivity in mono, hybrid and tri-hybrid nanofluids at varying temperature gradients. Furthermore, a comparative analysis of skin friction and heat transfer rates between copper, alumina and ferro composites is presented for optimising the nanofluid performance.
