Abstract
Chronic wounds are a major health challenge that require new treatment strategies. Hydrogels are promising drug delivery systems for chronic wound healing because of their biocompatibility, hydration, and flexibility. However, conventional hydrogels cannot adapt to the dynamic and complex wound environment, which involves low pH, high levels of reactive oxygen species, and specific enzyme expression. Therefore, smart responsive hydrogels that can sense and respond to these stimuli are needed. Crucially, smart responsive hydrogels can modulate drug release and eliminate pathological factors by changing their properties or structures in response to internal or external stimuli, such as pH, enzymes, light, and electricity. These stimuli can also be used to trigger antibacterial responses, angiogenesis, and cell proliferation to enhance wound healing. In this review, we introduce the synthesis and principles of smart responsive hydrogels, describe their design and applications for chronic wound healing, and discuss their future development directions. We hope that this review will inspire the development of smart responsive hydrogels for chronic wound healing.

Abstract
Polymer particles with precise diameters have been used as building blocks for fabricating well-defined and nanostructured materials. Polymer particles as building blocks for medical applications require both easily spatiotemporal manipulation and good biocompatibility. In this study, we designed zwitterionic polymer particles with photodimerizable groups on their surfaces and used ultraviolet (UV) light irradiation to photo-assemble them in aqueous media. After synthesizing zwitterionic polymer particles with diameters ranging from 100-200 nm via soap-free emulsion polymerization, maleimide moieties as photodimerizable groups were introduced onto the particle surfaces. UV light irradiation to an aqueous dispersion of zwitterionic polymer particles with photodimerizable groups induced their photo-assembling because interparticle bonding forms by photodimerization of the photodimerizable groups on the particle surfaces. The zwitterionic surface of their particle-assembled films effectively suppressed protein adsorption, cell adhesion, and platelet adhesion. The photoresponsive behaviour and bioinert surface of the zwitterionic polymer particles with photodimerizable groups indicate that they have several potential applications as bioinert building blocks for designing well-defined and nanostructured biomaterials used in biosensors, bioseparation and cell culture, and for modifying and repairing biomaterial surfaces in situ.

Abstract
This paper reports the facile preparation of dual stimuli-responsive gel particles that simultaneously respond to weakly acidic and reducing stimuli and the application of these gel particles as a drug delivery carrier. The dual stimuli-responsive gel particles composed of a pH-responsive polymer network cross-linked with reduction stimuli-responsive disulfide cross-links, and biocompatible poly(ethylene glycol) cross-links were prepared by soap-free emulsion polymerization. The resulting gel particles were colloidally stable at physiological ionic strength and had a diameter of approximately 200 nm with a narrow size distribution. The resulting gel particles slightly swelled in an acidic environment. On the other hand, the gel particles drastically swelled under simultaneous weakly acidic and reducing conditions because of the ionization of tertiary amino groups in the gel network and a decrease in the cross-linking density resulting from cleavage of the disulfide cross-links. When cells were treated with the gel particles, they were taken up by cells via the endocytosis pathway and distributed in the cytosol after endosomal escape by the proton sponge effect. In addition, a hydrophobic drug, doxorubicin (Dox), was loaded into the gel particles through hydrophobic interactions. Dox was released from the gel particles under weakly acidic and reducing conditions, while the Dox release was inhibited at neutral pH. The weakly acidic pH- and reduction stimuli-responsive release of Dox from gel particles was attributed to the drastic swelling of these particles. The fascinating properties of the dual stimuli-responsive gel particles suggest that they can provide a useful platform for designing intracellular drug delivery carriers.

Abstract
Pathogenic bacteria have become global threats to public health. Since the advent of antibiotics about 100 years ago, their use has been embraced with great enthusiasm because of their effective treatment of bacterial infections. However, the evolution of pathogenic bacteria with resistance to conventional antibiotics has resulted in an urgent need for the development of a new generation of antibiotics. The use of antimicrobial polymers offers the promise of enhancing the efficacy of antimicrobial agents. Of the various antibacterial polymers that effectively eradicate pathogenic bacteria, those that are nanoengineered have garnered significant research interest in their design and biomedical applications. Because of their high surface area and high reactivity, these polymers show greater antibacterial activity than conventional antibacterial agents, by inhibiting the growth or destroying the cell membrane of pathogenic bacteria. This review summarizes several strategies for designing nanoengineered antibacterial polymers, explores the factors that affect their antibacterial properties, and examines key features of their design. It then comments briefly on the future prospects for nanoengineered antibacterial polymers. This review thus provides a feasible guide to developing nanoengineered antibacterial polymers by presenting both broad and in-depth bench research, and it offers suggestions for their potential in biomedical applications.

Abstract
Recent advances and applications of biomolecule-responsive hydrogels, namely, glucose-responsive hydrogels, protein-responsive hydrogels, and nucleic-acid-responsive hydrogels are highlighted. However, achieving the ultimate purpose of using biomolecule-responsive hydrogels in preclinical and clinical areas is still at the very early stage and calls for more novel designing concepts and advance ideas. On the way toward the real/clinical application of biomolecule-responsive hydrogels, plenty of factors should be extensively studied and examined under both in vitro and in vivo conditions. For example, biocompatibility, biointegration, and toxicity of biomolecule-responsive hydrogels should be carefully evaluated. From the living body's point of view, biocompatibility is seriously depended on the interactions at the tissue/polymer interface. These interactions are influenced by physical nature, chemical structure, surface properties, and degradation of the materials. In addition, the developments of advanced hydrogels with tunable biological and mechanical properties which cause no/low side effects are of great importance.

Abstract
A selective adsorption/desorption of organoiodine compounds was achieved on poly(2-methoxyethyl acrylate)-analogue microspheres, wherein the side chains in the polymers act as halogen-bonding sites. These results demonstrate that the halogen-bonding sites in the side chains exhibit adequate specific affinity for organoiodine compounds. In addition, the water-swollen pMEA-analogue microspheres (microgels) showed a thermoresponsive swelling/deswelling behavior that permitted a controlled release of the organoiodine compounds upon changing the temperature. Thus, it seems plausible that a variety of problems associated with, e.g., the recovery of rare iodine-containing compounds, such as the marine-derived iodine compounds, the delivery of iodine-containing drugs, or the removal of halogen compounds from wastewater, could be resolved by polymer microspheres that exhibit controlled halogen bonding.

Abstract
Despite recent progress in vascularized composite allotransplantation (VCA), limitations including complex, high dose immunosuppression regimens, lifelong risk of toxicity from immunosuppressants, acute and most critically chronic graft rejection, and suboptimal nerve regeneration remain particularly challenging obstacles restricting clinical progress. When properly configured, customized, and implemented, biomaterials derived from the extracellular matrix (ECM) retain bioactive molecules and immunomodulatory properties that can promote stem cell migration, proliferation and differentiation, and constructive functional tissue remodeling. The present paper reviews the emerging implications of ECM-based technologies in VCA, including local immunomodulation, tissue repair, nerve regeneration, minimally invasive graft targeted drug delivery, stem cell transplantation, and other donor graft manipulation.

Abstract
The remarkable capability of nature to design and create excellent self-assembled nano-structures, especially in the biological world, has motivated chemists to mimic such systems with synthetic molecular and supramolecular systems. The hierarchically organized self-assembly of low molecular weight gelators (LMWGs) based on non-covalent interactions has been proven to be a useful tool in the development of well-defined nanostructures. Among these, the self-assembly of sugar-derived LMWGs has received immense attention because of their propensity to furnish biocompatible, hierarchical, supramolecular architectures that are macroscopically expressed in gel formation. This review sheds light on various aspects of sugar-derived LMWGs, uncovering their mechanisms of gelation, structural analysis, and tailorable properties, and their diverse applications such as stimuli-responsiveness, sensing, self-healing, environmental problems, and nano and biomaterials synthesis.

Abstract
Biomolecule-sensitive hydrogels that undergo volumetric changes in response to a target biomolecule such as glucose and proteins have become increasingly important because of their potential applications as smart biomaterials for constructing self-regulated drug-delivery systems (DDSs) and diagnostic systems. However, there have not been so many studies on biomolecule-sensitive hydrogels, due to difficulties in combining biomolecular recognition abilities with responsive functions within a hydrogel. This chapter introduces some strategies for designing biomolecule-sensitive hydrogels that exhibit swelling/shrinking behavior or sol-gel transition in response to the concentration of a target biomolecule. A standard strategy is to combine the molecular recognition events of biomolecules such as enzymes, lectins and antibodies with responsiveness of pH- and temperature-sensitive polymers. Another strategy uses biomolecular complexes like those of lectin-saccharide and antigen-antibody as dynamic cross-links of hydrogel networks. Designs of biomolecule-sensitive hydrogels will contribute significantly to develop smart DDSs in which specific amounts of drugs can be administered with monitoring specific biomolecules as diagnostic signals for several physiological changes. This chapter provides an overview of important researches about biomolecule-sensitive hydrogels for DDSs and diagnosis, focusing on saccharides, proteins, DNAs, etc. as target biomolecules.
