Pretreatment-free SERS sensing of microplastics using a self-attention-based neural network on hierarchically porous Ag foams

Low-cost detection systems are needed for the identification of microplastics (MPs) in environmental samples. However, their rapid identification is hindered by the need for complex isolation and pre-treatment methods. This study describes a comprehensive sensing platform to identify MPs in environmental samples without requiring independent separation or pre-treatment protocols. It leverages the physicochemical properties of macroporous-mesoporous silver (Ag) substrates templated with self-assembled polymeric micelles to concurrently separate and analyze multiple MP targets using surface-enhanced Raman spectroscopy (SERS). The hydrophobic layer on Ag aids in stabilizing the nanostructures in the environment and mitigates biofouling. To monitor complex samples with multiple MPs and to demultiplex numerous overlapping patterns, we develop a neural network (NN) algorithm called SpecATNet that employs a self-attention mechanism to resolve the complex dependencies and patterns in SERS data to identify six common types of MPs: polystyrene, polyethylene, polymethylmethacrylate, polytetrafluoroethylene, nylon, and polyethylene terephthalate. SpecATNet uses multi-label classification to analyze multi-component mixtures even in the presence of various interference agents. The combination of macroporous-mesoporous Ag substrates and self-attention-based NN technology holds potential to enable field monitoring of MPs by generating rich datasets that machines can interpret and analyze.

Development and evaluation of redox-responsive alginate–SS–ibuprofen derivative based anti-tumor target drug delivery system for the controlled release of doxorubicin

Nowadays, self-assembled polymeric micelles from amphiphilic polymer conjugates are urgently needed to enhance drug targeting and release efficiency. On account of the excellent properties of alginate and the redox-responsiveness of disulfide bonds, a redox-sensitive alginate–SS–ibuprofen derivative (LSA–SS–IBU) based anti-tumor target drug delivery system was created by attaching the hydrophobic ibuprofen (IBU) onto the hydrophilic alginate molecular skeleton through disulfide linkages for glutathione (GSH) triggered delivery of doxorubicin hydrochloride (DOX). The structure and self-assembly behavior of the synthesized LSA–SS–IBU was systematically evaluated by FT-IR spectrometer, 1H NMR spectrometer, fluorescence spectrophotometer (FM), transmission electron microscope (TEM) and dynamic light scattering (DLS). Furthermore, the in vitro release of drugs from the LSA–SS–IBU micelles loaded with DOX was examined, along with the assessment of their cytotoxicity to HeLa cells. The resultant LSA–SS–IBU had a critical micelle concentration (CMC) value of 0.19 mg/mL that was able to self-assemble into the spherical micelles with the particle size and zeta potential of 148.2 ± 4.3 nm (PDI = 0.25) and −47.2 ± 0.4 mV, respectively. At a mass ratio of 3:10 for DOX/LSA–SS–IBU, the LSA–SS–IBU micelles achieved drug loading ratio (DLR) and encapsulation efficiency (EE) values of 12.2 % and 46.3 %, respectively. Furthermore, the in vitro drug release study indicated that the total drug release percentage of the drug-encapsulated LSA–SS–IBU micelles in PBS with the presence of 10 mmol/L GSH for 12 h exceeded 67.0 %, demonstrating a substantial increase compared to that in GSH-free PBS. The in vitro cytotoxicity findings indicated that LSA–SS–IBU had good biocompatibility, while the IC50 value and the cell viability of DOX-loaded LSA–SS–IBU micelles cultured with HeLa cells for 48 h was 2.2 μg/mL and less than 20.1 %, respectively, which could significantly inhibit the growth of HeLa cells. Therefore, redox-responsive LSA–SS–IBU micelles had potential applications in cancer therapy for hydrophobic anti-tumor drug delivery.

Hyperoside-loaded TPGs/mPEG-PDLLA self-assembled polymeric micelles: preparation, characterization and in vitro/in vivo evaluation

Hyperoside (Hyp) self-assembled polymeric micelles (Hyp-PMs) were purposely developed to enhance aqueous solubility, in vivo availability and anti-oxidative effect of Hyp. In preparing Hyp-PMs, we employed the thin film dispersion method with the micelles consisting of TPGs and mPEG2000-PDLLA3000. The particle size, polydispersity index and zeta potential of Hyp-PMs were 67.42 ± 1.44 nm, 0.229 ± 0.015 and −18.67 ± 0.576 mV, respectively, coupled with high encapsulation efficiency （EE）of 90.63 ± 1.45% and drug loading (DL) of 6.97 ± 1.56%. Furthermore, the value of critical micelle concentration (CMC) was quite low, which indicated good stability and improved self-assembly ability of Hyp-PMs. Also, trend of in vitro Hyp release from Hyp-PMs demonstrated enhanced solubility of Hyp. Similarly, in comparison with free Hyp, oral bioavailability of Hyp-PMs was improved (about 8 folds) whilst half-life of Hyp-PMs was extended (about 3 folds). In vitro anti-oxidative effect showed obvious strong scavenging DPPH capability of Hyp-PMs, which may be attributed to its smaller size and better solubility. Altogether, Hyp-PMs may serve as a possible strategy to potentially enhance aqueous solubility, bioavailability and anti-oxidative effect of Hyp, which may play a key role in Hyp application in the pharmaceutical industries.

WITHDRAWN: Biodegradable Self-assembled polymeric Micelles based on Poly (ethylene oxide)-block-Polylactide block copolymer for sustained delivery of dapsone

Dapsone is the simplest antibiotic of sulphones that demonstrates its viability against various species of bacteria and protozoa. By restricting dihydrofolic acid synthesis through competition with para-amino benzoate, dapsone inhibits the growth of these microorganisms. Owing to its low aqueous solubility and non-specific distribution in the body, the applicability of dapsone is impeded. A control on pharmacokinetics and targeted delivery of drugs is deeply needed in order to reduce the side effects of the drug and make treatment more progressive. The aim of this study is to increase the bioavailability and efficacy of dapsone through the delivery of MeO-PEO 5K -b-PLA micelles. The effect of the length of the hydrophobic block (PLA) on micelles size, critical micelle concentration, entrapment efficiency, and release study is assessed. The PMs were prepared using the solvent evaporation process. The CMC of synthesized block copolymer was measured using a fluorescence-based method. The size and morphology of PMs was determined by dynamic light scattering (DLS) and atomic force microscopy (AFM). The entrapment efficiency and release kinetic behavior of MeO-PEO 5K -b-PLA based PMs were determined by UV-visible spectroscopy and dispersion method, respectively. The size of micelles increased and the rate of drug release decreased as the length of the PLA block increased. With copolymers having greater PLA block length, the maximum encapsulation efficiency of 89.58 percent for dapsone is attained. A comparison of dapsone's antibacterial activity against S. Aureus is performed and delivered by PMs. In comparison to pure drugs, the MIC for PMs loaded with dapsone has decreased. Morphological analysis based on AFM also verified the decrease in MIC.

Self-assembled magnetic polymeric micelles for delivery of quercetin: Toxicity evaluation on isolated rat liver mitochondria

Multifunctional nanocarriers as a promising platform could provide numerous opportunities in the field of drug delivery. Drug carriers loaded with both magnetic nanoparticles (MNPs) and therapeutic agents would allow the combination of chemotherapy with the possibility of monitoring or controlling the distribution of the nano vehicles in the body which may improve the effectiveness of the therapy. Furthermore, by applying these strategies, triggering drug release and/or synergistic hyperthermia treatment are also reachable. This study aimed to explore the potential of the quercetin (QUR) loaded magnetic nano-micelles for improving drug bioavailability while reducing the drug adverse effects. The bio-safety of developed QUR loaded magnetic nano-micelles (QMNMs) were conducted via mitochondrial toxicity using isolated rat liver mitochondria including glutathione (GSH), malondialdehyde (MDA), and the ferric reducing ability of plasma (FRAP). QMNMs with a mean particle size of 85 nm (PDI value of 0.269) and great physical stability were produced. Also, TEM images indicated that the prepared QMNMs were semi-spherical in shape. These findings also showed that the constructed QMNMs, as a pH-sensitive drug delivery system, exhibited a stable and high rate of QUR release under mildly acidic conditions pH (5.3) compared to neutral pH (7.4). The most striking result to emerge from the data is that an investigation of various mitochondrial functional parameters revealed that both QMNMs and QUR have no specific mitochondrial toxicity. Altogether, these results offer overwhelming evidence for the bio-safety of QMNMs and might be used as an effective drug delivery system for targeting and stimuli-responsive QUR delivery.

Tenoxicam-loaded polymeric micelles material: Formulation, optimization, and evaluation

The objective of the current study was to encapsulate Tenoxicam a poorly soluble drug within self-assembled polymeric micelles created from amphiphilic block copolymer poloxamer 407 to enhance its solubility and thus increasing oral bioavailability. Thin-film hydration technique was adapted in preparation of Tenoxicam loaded polymeric micelles based on different ratios of copolymer poloxamer 407 (ranging from 1:5 up to 1:90), selection of the best micellar formula was based on the values of entrapment efficiency (EE%), particle size (PS), polydispersity index (PDI), and rate of in vitro drug release, then lyophilization was done for selected formula. Prepared micellar solutions (PM1-PM10) were characterized and the best formula PM6 was chosen according to good EE% (84.05%), smaller particle size (33.07 ± 2.23 nm), lower PDI value (0.155), and higher in vitro drug release (81.43% ± 0.048), which further lyophilized and subjected for powder characterization. Fourier transform infrared spectroscopy (FTIR) and differential scanning calorimetry (DSC) indicated that TNX was encapsulated in polymeric micelle core, due to the disappearance of a characteristic peak of TNX. Saturated solubility of PM6 lyophilized powder showed an increase in aqueous solubility (122 times) compared with pure drug, while transmission electron microscopy (TEM) showed the polymeric micelles in images with a spherical structure, smooth surface, uniform particle size, and homogeneous distribution in an aqueous medium. It was concluded that the prepared amphiphilic copolymer micelles loaded with TNX exhibited significant improvement in drug solubility and consequently may enhance oral bioavailability and suggested to be used to prepare solid oral dosage form as an alternative to the marketed one with lower dose size and reduce drug side effects.

Self-assembled polymeric micelle as a novel mRNA delivery carrier

mRNA-based therapy has been evaluated in preclinical and clinical studies for the treatment of a wide variety of disease such as cancer immunotherapies and infectious disease vaccines. However, it remains challenging to development safe and efficient delivery system. Here, we have designed a novel self-assembled polymeric micelle based on vitamin E succinate modified polyethyleneimine copolymer (PVES) to delivery mRNA. In vitro, PVES could transfect mRNA into multiple cell lines such as HEK-293T, HeLa and Vero and the transfection efficiencies were much higher than PEI 25 k. In addition, the cytotoxicity of PVES was much lower than PEI 25 k. Furthermore, mice administered intramuscularly with PVES/SARS-CoV-2 mRNA vaccine induced potent antibody response and show no obvious toxicity. These results demonstrated the potential of PVES as a safe and effective delivery carrier for mRNA.

Tau-Targeted Multifunctional Nanoinhibitor for Alzheimer's Disease.

With the failure of various amyloid-β-targeted drugs for Alzheimer's disease (AD) in clinical trials, tau protein has gained growing attention as an alternative therapeutic target in recent years. The aggregation of tau exerts neurotoxicity, and its spreading in the brain is associated with increasing severity of clinical symptoms for AD patients; thus tau-targeting therapies hold great potential against AD. Here, a tau-targeted multifunctional nanoinhibitor based on self-assembled polymeric micelles decorated with tau-binding peptide is devised for AD treatment. Through the multivalent binding effect with the aggregating protein, this nanoinhibitor is capable of efficiently inhibiting tau protein aggregation, recognizing tau aggregates, and blocking their seeding in neural cells, thus remarkably mitigating tau-mediated cytotoxicity. Moreover, the formed nanoinhibitor-tau complex after binding is more easily degraded than mature tau aggregates, which will be conducive to enhance the therapeutic effect. We believe that this multifunctional nanoinhibitor will promote the development of new antitau strategies for AD treatment.

Self-Assembled Nanochaperones Inhibit the Aggregation of Human Islet Amyloid Polypeptide Associated with Type 2 Diabetes

Human islet amyloid polypeptide (hIAPP) aggregation is closely associated with dysfunction and apoptosis of pancreatic β-cells in type 2 diabetes (T2D). Accordingly, hIAPP amyloid inhibitors have shown promise against T2D. Here, by mimicking the function of natural molecular chaperones, nanochaperones (nChaps) based on self-assembled polymeric micelles with tunable surface microdomains for T2D treatment are reported. By capturing the aggregation-prone species of hIAPP onto the hydrophobic microdomains and segregating them by hydrophilic PEG chains, this kind of nChaps could effectively prevent hIAPP aggregation, block cell adhesion of hIAPP, facilitate hIAPP aggregates degradation and reduce hIAPP-related cytotoxicity. Therefore, our work will provide useful insights to develop a biomimetic strategy for the treatment of T2D.

Self-assembled polymeric micelles for targeted photodynamic therapy of human epidermal growth factor receptor 2 overexpressing breast cancer

Photodynamic therapy (PDT) has been extensively explored as a promising alternative therapeutic approach for many malignant tumors. However, the PDT system generally involves unsatisfactory tumor specificity and nonspecific accumulation of photosensitizers around the target cancer cells, leading to phototoxic damage to adjacent healthy normal cells. In this study, we developed pheophorbide a (Pheo a)/human epidermal growth factor receptor 2 (HER2) targeting peptide (epitope form, HLTV, PEG2-LTVSPWY)-co-conjugated methoxy poly(ethylene glycol)-block-poly(L-lysine hydrochloride) (PEG-PLL)/hyaluronic acid (HA) (P3H2) polymeric micelles via a self-assembly method for HER2-targeted PDT treatment for breast cancer, thereby enhancing the PDT efficacy. The synthesized P3H2 polymeric micelles were spherical, with an average diameter of 125.7 ± 21.2 nm in an aqueous solution. The results of in vitro cytotoxicity assays demonstrated that the P3H2 polymeric micelles significantly improved PDT efficacy on the SK-BR-3 cells due to the enhanced targeting ability. In addition, PDT treatment using the P3H2 polymeric micelles effectively killed breast cancer cells by inducing higher intracellular reactive oxygen species generation and apoptotic cell death. In particular, the three-dimensional cell culture model proved the synergistic PDT efficacy using P3H2 polymeric micelles on the SK-BR-3 cells. Based on these results, the PDT treatment using P3H2 polymeric micelles can serve as a highly effective therapeutic modality for breast cancer.

PH-Responsive Amphiphilic Polyether Micelles with Superior Stability for Smart Drug Delivery.

Despite widespread interest in the amphiphilic polymeric micelles for drug delivery systems, it is highly desirable to achieve high loading capacity and high efficiency to reduce the side effects of therapeutic agents while maximizing their efficacy. Here, we present a novel hydrophobic epoxide monomer, cyclohexyloxy ethyl glycidyl ether (CHGE), containing an acetal group as a pH-responsive cleavable linkage. A series of its homopolymers, poly(cyclohexyloxy ethyl glycidyl ether)s (PCHGEs), and block copolymers, poly(ethylene glycol)-block-poly(cyclohexyloxy ethyl glycidyl ether)s (mPEG-b-PCHGE), were synthesized via anionic ring-opening polymerization in a controlled manner. Subsequently, the self-assembled polymeric micelles of mPEG-b-PCHGE demonstrated high loading capacity, excellent stability in biological media, tunable release efficiency, and high cell viability. Importantly, quantum mechanical calculations performed by considering prolonged hydrolysis of the acetal group in CHGE indicated that the CHGE monomer had higher hydrophobicity than three other functional epoxide monomer analogues developed. Furthermore, the preferential cellular uptake and in vivo therapeutic efficacy confirmed the enhanced stability and the pH-responsive degradation of the amphiphilic block copolymer micelles. This study provides a new platform for the development of versatile smart polymeric drug delivery systems with high loading efficiency and tailorable release profiles.

Nanoparticulate tablet dosage form of lisofylline-linoleic acid conjugate for type 1 diabetes: in situ single-pass intestinal perfusion (SPIP) studies and pharmacokinetics in rat.

Lisofylline (LSF) is an anti-inflammatory molecule with high aqueous solubility and rapid metabolic interconversion to its parent drug, pentoxifylline (PTX) resulting in very poor pharmacokinetic (PK) parameters, necessitating high dose and dosing frequency. In the present study, we resolved the physicochemical and pharmacokinetic limitations associated with LSF and designed its oral dosage form as a tablet for effective treatment in type 1 diabetes (T1D). Self-assembling polymeric micelles of LSF (lisofylline-linoleic acid polymeric micelles (LSF-LA PLM)) were optimized for scale-up (6 g batch size) and lyophilized followed by compression into tablets. Powder blend and tablets were evaluated as per USP. LSF-LA PLM tablet so formed was evaluated for in vitro release in simulated biological fluids (with enzymes) and for cell viability in MIN-6 cells. LSF-LA PLM in tablet formulation was further evaluated for intestinal permeability (in situ) along with LSF and LSF-LA self-assembled micelles (SM) as controls in a rat model using single-pass intestinal perfusion (SPIP) study. SPIP studies revealed 1.8-fold higher oral absorption of LSF-LA from LSF-LA PLM as compared to LSF-LA SM and ~5.9-fold higher than LSF (alone) solution. Pharmacokinetic studies of LSF-LA PLM tablet showed greater Cmax than LSF, LSF-LA, and LSF-LA PLM. Designed facile LSF-LA PLM tablet dosage form has potential for an immediate decrease in the postprandial glucose levels in patients of T1D.

Poly(2-ethyl-2-oxazoline-co-ethyleneimine)-block-poly(ε-caprolactone) based micelles: synthesis, characterization, peptide conjugation and cytotoxic activity

Here we present self-assembled polymeric micelles as potential delivery systems for therapeutic agents with highly tunable properties.

First electrochemical synthesis of mesoporous RhNi alloy films for an alkali-mediated hydrogen evolution reaction

The mesoporous RhNi alloy films are synthesized by controlling the concentration of Rh precursor, applied potentials, and pH via the electrochemical co-deposition method with self-assembled polymeric micelles templates for enhancing electrocatalytic properties.

A smart drug delivery system responsive to pH/enzyme stimuli based on hydrophobic modified sodium alginate

A biocompatible dual-stimuli responsive drug delivery for hydrophobic drugs based on self-assembled polymeric micelles was presented. Hydrophobic modified alginate (HMA), used dodecyl glycidyl ether as a hydrophobic group, could form self-assembled micelles in aqueous solution above the critical micelle concentration. Doxorubicin (DOX) was chosen as a model drug and successfully loaded in HMA micelles. The percentage of drug loading efficiency of the HMA was determined as 65.4% by using fluorescence measurement. The pH-triggered and enzyme-triggered release behavior of DOX from DOX-HMA micelles indicated that the release of DOX was accelerated in acidic medium and that the release rate was dramatically enhanced in the presence of Alpha-L-fucosidase. It was found that almost 80% DOX was released from the DOX-HMA micelles in the presence of AFU at pH 5.5. Moreover, in vitro drug release studies exhibited that the DOX-HMA was effectively taken up by the cancer cells, and the blank micelles showed low toxicity toward the cancer cells, while the drug loaded micelles had high toxicity, even than the free drugs. These results demonstrate that HMA may serve as a general platform for therapeutic delivery.

Nanochaperones Mediated Delivery of Insulin

Insulin would undergo unfolding and fibrillation under stressed conditions, which may cause serious biotechnological and medical problems. Herein, by mimicking the structure and functions of natural chaperones HSP70s, self-assembled polymeric micelles are used as nanochaperones for the delivery of insulin. The confined hydrophobic domains on the surface of nanochaperones adsorb partially unfolded insulin, inhibiting the aggregation and fibrillation and enhancing the stability of insulin. The bioactivity of insulin is well-reserved after incubation with the nanochaperones at 37 °C for 7 d or heating at 70 °C for 1 h. The stealthy poly(ethylene glycol) chains around the confined domains protect the adsorbed insulin from enzymatic degradation and prolong the circulation time. More importantly, the excellent glucose sensitivity of the hydrophobic domains enables the nanochaperones to release and refold insulin in native form in response to hyperglycemia. This kind of nanochaperone may offer a hopeful strategy for the protection and delivery of insulin.

Scalable Self-Assembling Micellar System for Enhanced Oral Bioavailability and Efficacy of Lisofylline for Treatment of Type-I Diabetes

The study summarizes the development of an orally active nanoformulation of a potent but one of the least explored molecules, lisofylline (LSF), in type 1 diabetes (T1D). LSF undergoes rapid metabolism, resulting in poor oral bioavailability and short half-life. In this work, to improve its pharmacokinetic (PK) properties, LSF was encapsulated in the form of its ester prodrug [LSF-linoleic acid (LA) prodrug] into biodegradable self-assembling polymeric micelles [LSF-LA PLM, size: 149.3 nm; polydispersity index: 0.209; critical micelle concentration (cmc); 5.95 μg/mL and Nagg: 14.82 at 10 cmc] of methoxypoly(ethylene glycol)-b-poly(carbonate-co-l-lactide) (mPEG-b-P(CB-co-LA)) block copolymer. LSF-LA PLM was found to be equally effective as the LSF-LA prodrug in cell culture studies in insulin-secreting MIN6 cells and showed excellent stability in simulating biological fluids and plasma. PK of LSF-LA PLM (10 mg/kg dose) revealed a significant improvement in oral bioavailability of LSF (74.86%; 3.3-fold increase in comparison to free LSF) and drastic reduction in the drug metabolism. Further, LSF-LA PLM showed a significant reduction in fasting glucose levels and increase in insulin levels by intraperitoneal as well oral routes in a streptozotocin (STZ)-induced T1D rat model. Production of inflammatory cytokines (TNF-α and IFN-γ) and different biochemical markers for liver and kidney functions were much reduced in diabetic animals after treatment with LSF-LA PLM. LSF-LA PLM-treated pancreatic sections showed minimal infiltration of CD4+ and CD8+ T-cells as indicated by hematoxylin/eosin staining and immunohistochemical analysis.

Chitosan Oleate Coated Poly Lactic-Glycolic Acid (PLGA) Nanoparticles versus Chitosan Oleate Self-Assembled Polymeric Micelles, Loaded with Resveratrol.

Chitosan oleate (CS-OA), a chitosan salt with amphiphilic properties, has demonstrated the ability to self-assemble in aqueous environment to give polymeric micelles useful to load poorly soluble drugs. More recently, CS-OA was proposed to stabilize nanoemulsions during the preparation by emulsification and solvent evaporation of poly lactic-glycolic acid (PLGA) nanoparticles (NPs) loaded with curcumin. Positive mucoadhesive behavior and internalization properties were demonstrated for these NPs attributable to the presence of positive charge at the NP surface. In the present paper, two CS-OA-based nanosystems, micelles and PLGA NPs, were compared with the aim of elucidating their physico-chemical characteristics, and especially their interaction with cell substrates. The two systems were loaded with resveratrol (RSV), a hydrophobic polyphenol endowed with anti-cancerogenic, anti-inflammatory, and heart/brain protective effects, but with low bioavailability mainly due to poor aqueous solubility. Calorimetric analysis and X-ray spectra demonstrated amorphization of RSV, confirming its affinity for hydrophobic domains of polymeric micelles and PLGA core of NPs. TGA decomposition patterns suggest higher stability of PLGA-NPs compared with polymeric micelles, that anyway resulted more stable than expected, considering the RSV release profiles, and the cell line interaction results.

Preparation and characterization of glutathione-responsive polymeric micelles functionalized with core cross-linked disulfide linkage for curcumin delivery

Conventional self-assembled polymeric micelles typically lose their loaded drugs after systemic administration. To resolve this issue, the aim of the present study was to develop a novel polymer, methoxy-poly (ethylene glycol)-block-poly (d, l-lactic acid) grafted with four lipoic acids (mPEG-PLA-(LA)4), to prepare curcumin-loaded core cross-linked polymeric micelles (CCM). Nitrogen and alkalescent buffer (pH 8.5) were beneficial for cross-linking, and the cross-linking was nearly complete within 30 min. The micelle preparation parameters were optimized through both a single-factor experiment and orthogonality test. The choice of cryoprotector had the most important effect on micelle solution reconstruction and almost challenged our perceptions about cryoprotector. In addition the drug loading capacity greatly affected the stability of micelles. Moreover, a method for determining the cross-linking density was established, and the result of gel permeation chromatography indirectly demonstrated that dozens of polymers had successfully formed CCM. The CCM significantly enhanced stability under non-reductive conditions and could be reversibly broken in a reductive environment. Curcumin-loaded CCM also showed glutathione-response cytotoxicity to cancer cells. Overall, this fundamental study suggests CCM as a potential carrier for achieving improved controlled drug delivery.
