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.

Integrating multimodality bioimaging and multiple stimuli-responsive controlled drug release properties into one single nanosystem for therapeutic application is highly desirable but still remains a challenge. Herein, we coated a hollow mesoporous silica shell on to upconversion nanoparticles (UCNPs) and conjugated pillarene-based supramolecular valves on to surface of UCNPs@hm-SiO2 using amine-coumarin phototriggers to obtain the multifunctional nanoparticles, UCNPs@hm-SiO2-Cou-Cys-DOX/WP[5]. Benefiting from the core shell structured UCNPs, the UCNPs@hm-SiO2-Cou-Cys-DOX/WP[5] can serve as efficient contrast agents for upconversion luminescence and T-1-weighted magnetic resonance imaging in vitro/in vivo. More importantly, depending on exquisitely designed supramolecular valves, UCNPs@hm-SiO2-Cou-Cys-DOX/WP[5] can realize zero-premature release under normal physiological conditions (pH 7.4), which produces minimal damage to normal tissue, whereas this nanosystem can respond to several disease-related signals, including acid (most cancers), alkali (metabolic alkalosis), and Zn2+ (Alzheimer’s disease), along with two external stimuli, including near-infrared (NIR) light and reductive electrical potential, via altering the spatial structure of pseudorotaxanes, disassembling the molecular stalks, or undergoing photochemical reactions, ultimately resulting in opening of the gatekeepers and release of encapsulated drugs. The multifunctional UCNP-based nanoparticles were endowed with such quintuple stimuli-responsive controlled release characteristics. Specifically, in anticancer application, the rational utilization of the two of them, acid and NIR light, could regulate the release amount and rate of DOX from UCNPs@hm-SiO2-Cou-Cys-DOX/WP[S], accelerate the accumulation of DOX in cell nuclei, and thereby promote the cancer cell apoptosis, indicating that the nanomaterials have promising application in cancer treatment. This study provides a novel design strategy for constructing multifunctional UCNP-based nanoparticles with multiple stimuli-responsive drug release features, which have great potential in diagnosis and therapy of relevant diseases as theranostic nanomedicines.

Volumetric muscle loss (VML) injuries characterized by critical loss of skeletal muscle tissues result in severe functional impairment. Current treatments involving use of muscle grafts are limited by tissue availability and donor site morbidity. In this study, we designed and synthesized an implantable glycosaminoglycan-based hydrogel system consisting of thiolated hyaluronic acid (HA) and thiolated chondroitin sulfate (CS) crosslinked with poly(ethylene glycol) diacrylate to promote skeletal muscle regeneration of VML injuries in mice. The HA-CS hydrogels were optimized with suitable biophysical properties by fine-tuning degree of thiol group substitution to support C2C12 myoblast proliferation, myogenic differentiation and expression of myogenic markers MyoD, MyoG and MYH8. Furthermore, in vivo studies using a murine quadriceps VML model demonstrated that the HA-CS hydrogels supported integration of implants with the surrounding host tissue and facilitated migration of Pax7(+) satellite cells, de novo myofiber formation, angiogenesis, and innervation with minimized scar tissue formation during 4-week implantation. The hydrogel-treated and autograft-treated mice showed similar functional improvements in treadmill performance as early as 1-week post-implantation compared to the untreated groups. Taken together, our results demonstrate the promise of HA-CS hydrogels as regenerative engineering matrices to accelerate healing of skeletal muscle injuries.
