Doxorubicin (DOX) resistance, which results in a reduced accumulation of DOX in the nucleus and hence decreased DNA damage, is a major challenge for chemotherapy against hepatocellular carcinoma. In this paper, we combined chemotherapy with photodynamic therapy (PDT) to combat DOX-resistant human hepatocellular carcinoma cells. We have prepared the polymeric micelles conjugating with DOX and zinc(II) phthalocyanine (ZnPc) through a pH-responsive hydrazone linker and a glutathione (GSH)-responsive disulfide linker, respectively. The polymeric micelles (DOX-ZnPc-micelles) exhibited a spherical shape with a size of about 98 mn diameter and showed excellent stability in aqueous solution. Due to the self-quenching of the ZnPc inside the micelles, DOX-ZnPc-micelles did not emit fluorescence upon red light irradiation. Drug release experiments verified that DOX and ZnPc could be released under acidic conditions and reducing environments, respectively. A higher concentration of DOX was internalized into DOX-resistant R-HepG2 cells through the delivery of polymeric micelles when compared with the free DOX, hence DOX-ZnPc-micelles exhibited a significant enhancement in anticancer activity. The IC50 value of DOX against R-HepG2 cells was found to be 21 mu M when combined with PDT and it was 5-fold less than that of a single treatment of DOX (102 mu M). The DOX-ZnPc-micelles could induce cell apoptosis and necrosis on R-HepG2 cells by combined therapeutic modalities, while these micelles induced only apoptosis on IiepG2 cells. We have demonstrated that utilization of polymeric micelles can significantly enhance the cellular uptake and cytotoxicity of DOX against R-HepG2 cells when compared with free DOX. Moreover, PDT can act as an adjuvant therapeutic modality and combine with chemotherapy to further improve therapeutic efficacy. Overall speaking, DOX-ZnPc-micelles can overcome DOX resistance and induce a synergistic therapeutic effect against DOX-resistant R-HepG2 cells, hence improving the therapeutic efficacy when compared with monotherapy.

A compressive strain applied to bilayer films (e.g., a thin film adhered to a thick substrate) can lead to buckled or wrinkled morphologies, which has many important applications in stretchable electronics, anticounterfeit technology, and high-precision micrometrology and nano-metrology. A number of buckling-based metrology methods have been developed to quantify the residual stress and viscoelastic properties of polymer thin films. However, in some systems (e.g., solvent-induced swelling or thermal strain), the compressive strain is unknown or difficult to measure. We present a quantitative method of measuring the compressive strain of wrinkled polymer films and coatings with knowledge of the skin thickness, wrinkle wavelength, and wrinkle amplitude. The derived analytical expression is validated with a well-studied model system, e.g., a stiff, thin film bonded to a thick, compliant substrate. After validation, we use our expression to quantify the applied swelling strain of previously reported wrinkled poly(styrene-alt-maleic anhydride) brush surfaces. Finally, the applied strain is used to rationalize the observed persistence length of aligned wrinkles created during atomic force microscopy lithography and subsequent solvent exposure.

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.

Microcarriers, including crosslinked porous gelatin beads (Cultispher G) are widely used as cell carriers for cell therapy applications. Microcarriers can support a range of adherent cell types in stirred tank bioreactor culture, which is scalable up to several thousands of liters. Cultispher G in particular is advantageous for cell therapy applications because it can be dissolved enzymatically, and thus cells can be harvested without the need to perform a large-scale cell-bead filtration step. This enzymatic dissolution, however, is challenged by the slow degradation of the carriers in the presence of enzymes as new extracellular matrix is being deposited by the proliferating cells. This extended dissolution timelimits the yield of cell recovery while compromising cellular viability. We report herein the development of crosslinked porous gelatin beads that afford rapid, stimuli-triggered dissolution for facile cell removal using human mesenchymal stem cells (hMSC) as a model system. We successfully fabricated redox-sensitive beads (RS beads) and studied their cell growth, dissolution time and cell yield, compared to regular gelatin-based beads (Reg beads). We have shown that RS beads allow for much faster dissolution compared to Reg beads, supporting better hMSC detachment and recovery following 8 days of culture in spinner flasks, or in 3L bioreactors. These newly synthesized RS beads show promise as cellular microcarriers and can be used for scale-up manufacturing of different cell types while providing on-demand degradation for facile cell retrieval.

Nanocarriers have provided a new platform for the selective delivery of therapeutic agents into targeted cells and tissues using safe, efficient, and tractable routes. In particular, the integration of multiple therapeutic/diagnostic modalities into a single system has the great potential of enhancing theranostic efficiency against serious diseases with reduced side effects. In this study, a new light-triggered theranostic system using photosensitizer-conjugated gold nanorods (AuNR) with glutathione (GSH)-sensitive linkages was developed for cancer imaging and combinational phototherapy of photodynamic therapy (PDT) and photothermal therapy (PTT) to achieve a synergistic cancer treatment. AuNRs with various aspect ratios were prepared as photothermal agents, and then a folic acid (FA)-PEG block copolymer (FAP) and pheophorbide a (Pheo) were chemically conjugated to the surface of AuNRs for active tumor targeting and PDT, respectively. The configuration of Pheo-conjugated AuNR nanocarriers has been precisely controlled through adjusting the feed composition ratio and the relationship between aspect ratio and absorption band of AuNRs. In particular, an AuNR with an aspect ratio of 3.84 and longitudinal plasmon resonance at 873 nm (Pheo-conjugated AuNR100) exhibited superior performance in singlet oxygen generation, photothermal conversion effect, and GSH-mediated selective release of Pheo. Moreover, it also showed tumor targeting activity and a PDT-PTT synergistic effect. These results indicate that this multifunctional AuNR system with tumor targeting ability and GSH-sensitive linkages would be highly efficient for noninvasive cancer treatment by integrating cancer imaging diagnostics and synergistic therapy.

Polymeric prodrug-based delivery systems have been extensively studied to find a better solution for the limitations of a single drug and to improve the therapeutic and pharmacodynamics properties of chemotherapeutic agents, which can lead to efficient therapy. In this study, redox-responsive disulfide bond-containing amphiphilic heparin-chlorambucil conjugated polymeric prodrugs were designed and synthesized to enhance anti-tumor activities of chlorambucil. The conjugated prodrug could be self-assembled to form spherical vesicles with 61.33% chlorambucil grafting efficiency. The cell viability test results showed that the prodrug was biocompatible with normal cells (HaCaT) and that it selectively killed tumor cells (HeLa cells). The uptake of prodrugs by HeLa cells increased with time. Therefore, the designed prodrugs can be a better alternative as delivery vehicles for the chlorambucil controlled release in cancer cells.

New bench-stable reagents with two diazonium sites were designed and synthesized for protein crosslinking. Because of the faster diazonium-tyrosine coupling reaction, hydrogels from the crosslinking of tobacco mosaic virus and the reagent DDA-3 could be prepared within 1 min at room temperature. Furthermore, hydrogels with the introduction of disulfide bonds viaDDA-4 could be chemically degraded by dithiothreitol. Our results provided a facile approach for the direct construction of virus-based hydrogels.

Deep tumor penetration, long blood circulation, rapid drug release, and sufficient stability are the most concerning dilemmas of nano-drug-delivery systems for efficient chemotherapy. Herein, we develop reduction/oxidation-responsive hierarchical nanoparticles co-encapsulating paclitaxel (PTX) and pH-stimulated hyaluronidase (pSH) to surmount the sequential biological barriers for precise cancer therapy. Poly(ethylene glycol) diamine (PEG-dia) is applied to collaboratively cross-link the shell of nanoparticles self-assembled by a hyaluronic acid-stearic acid conjugate linked via a disulfide bond (HA-SS-SA, HSS) to fabricate the hierarchical nanoparticles (PHSS). The PTX and pSH coloaded hierarchical nanoparticles (PTX/pSH-PHSS) enhance the stability in normal physiological conditions and accelerate drug release at tumorous pH, and highly reductive or oxidative environments. Functionalized with PEG and HA, the hierarchical nanoparticles preferentially prolong the circulation time, accumulate at the tumor site, and enter MDA-MB-231 cells via CD44-mediated endocytosis. Within the acidic tumor micro-environment, pSH would be partially reactivated to decompose the dense tumor extracellular matrix for deep tumor penetration. Interestingly, PTX/pSH-PHSS could be degraded apace by the completely activated pSH within endo/lysosomes and the intracellular redox micro-environment to facilitate drug release to produce the highest tumor inhibition (93.71%) in breast cancer models.

For next-generation electronics, it is crucial to be able to accurately mimic the nature of human skin and develop skin-inspired materials and devices for electronic skin (e-skin) applications. However, it is a great challenge to design such a materials because they require the complex integration of stretchability, skin adhesiveness, transparency, healability, and tactile sensing. Herein, we present the first dual covalently reversible dynamic bond-based polymer that can be integrated with various functional materials and used as a skin-like sensor. A series of polymers was designed using polypropylene glycol (PPG)-based polyurethane (PU) as the polymer backbone, and these polymers could integrate two types of covalent reversible dynamic bonds, Diels-Alder and disulfide bonds, in one polymer for the first time. Based on our design, a polymer was created with the advantages of high stretchability, fast healing abilities (60 degrees C, 5 min), skin adhesion, recyclability, high transparency, and tactile sensing abilities. We provide an alternative strategy for the construction of skin-inspired multifunctional materials for e-skin applications.
