Dual and multi-stimuli responsive polymeric nanoparticles that can respond to two or more signals have been demonstrated as prospective drug carriers with enhanced tumor accumulation and on-demand drug release profiles. In this study, dextran-based (Dex-SS) nanogels were developed via a facile method based on the disulfide containing Schiff base formation between polyaldehyde dextran and cystamine in water-in-oil inverse microemulsion. Acidic and reductive (GSH) environment sensitive degradation behaviors of the resulted nanogels were investigated by morphology analysis of the treated nanogels using SEM imaging. Doxorubicin (DOX) was covalently conjugated into the dextran nanogels via Schiff base linkages, and pH/GSH dual sensitive drug release profiles were demonstrated. Effective cell uptake of the DOX-loaded nanogels was finally identified by human cancer cell line of H1299. Take advantage of the acidic and reductive tumor microenvironment, the dual-stimuli responsive Dex-SS nanogels can serve as micmenvironment-sensitive drug delivery systems for tumor therapy.

This study aimed to develop an efficient step-by-step osteosarcoma (OS)-targeting liposome system functionalized with a redox-cleavable, bone- and cluster of differentiation 44 (CD44)-dual-targeting polymer. Furthermore, the effect of coadministration of a tumor-penetrating peptide, internalizing RGD (iRGD), was investigated. First, a bone-targeting moiety, alendronate (ALN), was conjugated with hyaluronic acid (HA), a ligand for CD44. This ALN-HA conjugate was coupled with DSPE PEG(2000)-COOH through a bioreducible disulfide linker (-SS-) to obtain a functionalized lipid, ALN-HA-SS-L, to be postinserted into preformed liposomes loaded with doxorubicin (DOX). The roles of ALN, HA, and the redox sensitivity of the ALN-HA-SS-L liposomes (ALN-HA-SS-L-L) in the anti-OS effect were critically evaluated against various reference liposomal formulations (with only ALN, HA, or redox sensitivity). ALN-HA-SS-L-L displayed a zeta potential of -26.07 +/- 0.32 mV and selectively disassembled in the presence of a reducing agent, 10 mM glutathione, which can be found in cancer cells. cells. Compared to various reference liposomes, ALN-HA-SS-L-L/DOX had significantly higher cytotoxicity to human OS MG-63 cells alongside high and rapid cellular uptake. In the orthotopic OS nude mouse models, ALN-HA-SS-L-L/DOX showed remarkable tumor growth suppression and prolonged survival time. This result was further improved by the coadministration of iRGD. The antitumor effects of various liposomes were ranked in the same order as the degree of tumor biodistribution shown by in vivo/ex vivo imaging: ALN-HA-SS-L-L coadministered with iRGD > ALN-HA-SS-L-L > HA-SS-L-L > HA-L-L > PEG-L> free drug. ALN-HA-SS-L-L/DOX also reduced the cardiotoxicity of DOX and lung metastases. Overall, this study demonstrated that ALN-HA-SS-L-L/DOX, equipped with bone- and CD44-dual-targeting abilities and redox sensitivity, could be a promising OS-targeted therapy. The efficacy could also be augmented by coadministration of iRGD.

Compared with liquid electrolytes, the solid polymer electrolyte (SPE), which possesses improved thermal and mechanical stability, is believed the broadest potential application for satisfying the safety needs of advanced electro-chemical devices. However, some breakable SPEs could lead to catastrophic failure of batteries that triggered by a short circuit. In the present contribution, a new class of SPE containing disulfide bonds and urea groups is reported. The hydrogen bonding between the urea groups and disulfide metathesis reaction endows the SPE with a high level of self-healing without external stimuli at room temperature as well as ultrafast self-healing at elevated temperatures. The completely healed SPE with extreme damage shows a high self-healing efficiency and no changes in the ionic conductivity and cycling performance of the solid-state lithium-metal/LiFePO4 cell compared to the pristine one.

A well-defined functional star polymer nanoparticle was prepared using an “ arm first” approach via RAFT polymerization. In this work, N-adamantylacrylamide and N-succinimidyl acrylate were copolymerized with N-isopropylacrylamide sucessfully. The obtained diblock copolymer regarded as an “ arm” endowed the star polymer with multiple conjugate functions. By adjusting the amount of crosslinking agent, the size and polydispersity of the star polymer were controlled. With the star polymer as the scaffold, a sequential multi-enzyme system was constructed, where HRP was placed in the inner layer through covalent conjugation, and b-cyclodextrin-modified GOx was assembled in the outer layer through hostguest recognition. More interestingly, the activity of the enzyme modified by b-cyclodextrin was improved. In addition to the enhanced thermal stability, this multienzyme system also exhibited a reduced Km value (from 2.18 mM to 0.39 mM) and an excellent substrate affinity. The specificity constant (Kcat/Km) for GOx in the star polymer@ HRP@ GOx system was 1.7-fold higher than that of the free HRP with free GOx system. This strategy will promote the development of biocatalysis reactions and biosensors as a promising method.

Molecular probes featuring promising capabilities including specific targeting, high signal-to-noise ratio, and in situ visualization of deep tissues are in great demand for tumor diagnosis and therapy. F-19 magnetic resonance imaging (MRI) techniques incorporating stimuli-responsive probes are anticipated to be highly beneficial for specific detection and imaging of tumors because of negligible background and deep tissue penetration. Herein, we report a cascaded multi-responsive self-assembled nanoprobe, which enables sequential redox-triggered and near-infrared (NIR) irradiation-induced F-19 MR signal activation/amplification for sensing and imaging. Specifically, we designed and synthesized a cascaded multiresponsive F-19-bearing nanoprobe based on the self-assembly of amphiphilic redox-responsive F-19-containing polymers and NIR-absorbing indocyanine green (ICG) molecules. It could realize the activation of F-19 signals in the reducing tumor microenvironment and subsequent signal amplification via the photothermal process. This stepwise two-stage activation/amplification of F-19 signals was validated by F-19 NMR and MRI both in vitro and in vivo. The multiresponsive F-19 nanoprobes capable of cascaded F-19 signal activation/amplification and photothermal effect exertion can provide accurate sensing and imaging of tumors.

A series of polystyrene- and poly(methyl methacrylate)-dithioesters was subjected to aminolysis under ambient atmospheric conditions, i.e., in the presence of oxygen. Polymer disulfide coupling by oxidation occurred within tens of minutes and the yield of disulfide-coupled polymer increased with decreasing polymer molar mass. Oxidation of thiolates is usually an unwanted side reaction, here it is employed to obtain exclusively polymeric mixed disulfides through in situ aminolysis/functionalization in the presence of a thiol. The in situ aminolysis/functionalization in the presence of a disulfide, Ellman’s reagent or polymer disulfide, resulted in the exclusive formation of polymer-dithionitrobenzoic acid, which can be further reacted with a thiol to exchange the terminal functionality, or block copolymer with dynamic disulfide linker, respectively.

To achieve a high stability in physiological environment and rapid intracellular drug release, a biodegradable zwitterionic triblock copolymer with a disulfide-linked poly-epsilon-caprolactone and polycarboxybetaine methacrylate (PCBMA-SS-PCL-SS-PCBMA) was prepared for micellar carrier to delivery doxorubicin (DOX) into tumor cells. PCBMA-SS-PCL-SS-PCBMA was obtained by following steps: i) introducing disulfide bonds through end-group modification of PCL diol with cystamine dihydrochloride; ii) preparing PCL-RAFT macromolecular chain transfer agent by EDC/NHS chemistry; iii) RAFT polymerization of zwitterionic monomer. Self-assembling from PCBMA-SS-PCL-SS-PCBMA, polymeric micelles had many advantages, such as ultra-low protein absorption in serum and obvious reduction-responsiveness in the presence of DTT. Furthermore, DOX-loaded micelles exhibited high stability upon centrifugation and lyophilization, a fast intracellular drug release and enhanced drug efficacy due to GSH-triggered PCBMA shell shedding and micellar reassembling. Thus, the polymeric micelles integrated several functions and properties could be prospectively utilized as valuable nanocarriers in cancer chemotherapeutics.

Natural hydrogels are widely investigated for biomedical applications because of their structures similar to extracellular matrix of native tissues, possessing excellent biocompatibility and biodegradability. However, they are often susceptible to mechanical disruption. In this study, self-healing hyaluronic acid (HA) hydrogels are fabricated through a facile dynamic covalent Schiff base reaction. Dialdehyde-modified HA (AHA) precursor was synthesized, and then the AHA/cystamine dihydrochloride (AHA/Cys) hydrogels were formed by blending AHA and Cys at acidic pH levels. By varying Cys to AHA ratio, the hydrogel morphology, swelling and kinetics of gelation could be controlled. Gelation occurred fast, which was predominantly attributed to Schiff base reaction between the dialdehyde groups on AHA and amimo groups on Cys. The hydrogel exhibited improved mechanical properties with increase in Cys content. Furthermore, due to dynamic imine bonds, this hydrogel demonstrated excellent self-healing ability based on the stress after mechanical disruption. Also, it was found to be pH-responsive and injectable. Taken together, this kind of hyaluronic acid hydrogel can provide promising future for various biomedical applications in drug delivery, bioprinting, smart robots and tissue regeneration.

In this work, two novel boronate affinity monolithic materials able to extract glycopeptides within a polypropylene syringe are described and compared. The first material was synthesized from glycidyl methacrylate (GMA)-based monoliths modified with poly-3-mercaptopropyl-methylsiloxane (PMPMS) followed by attachment of 4-vinylphenylboronic acid (VPBA) via thiol-ene click reaction. The second material was prepared by using gold nanoparticle (AuNP)-modified monoliths as substrate followed by subsequent attachment of PMPMS and VPBA. The resulting materials were used as sorbents for solid-phase extraction (SPE) to selectively preconcentrate glycopeptides from horseradish peroxidase (HRP) digests. The material that gave the superior performance was that prepared with AuNPs due to the presence of abundant boronic acid groups, being its practical applicability also examined. The hybrid material exhibited a satisfactory efficiency of glycopeptide enrichment (identifying 24 glycopeptides from a total of 27) in mixture of tryptic digests of HRP and bovine serum albumin (BSA) (1:100, w/w). The sorbent shows low sensitivity (0.5 fmol/?L), good adsorption capacity (25 mg g-1) and suitable reusability (over 10 times). Moreover, the hybrid monolith was successfully applied to the selective enrichment of glycopeptides from human serum digests, without any pretreatment, in which 85 glycopeptides were identified by nano-LC-MS/MS, suggesting a great potential for application in glycoproteome field.
