Summary: Nowadays, the combination of biomedical research and material sciences has led to the development of smart materials that can effectively solve microbial contamination problems. In this study, a new drug delivery platform composed of sodium alginate, beta-carboxyethyl acrylate, and acrylamide was prepared and characterized. Swelling studies showed that the hydrogel without drugs had a higher swelling rate compared to drug-loaded hydrogels. The hydrogel demonstrated a pH-dependent drug release rate and exhibited comparable antibacterial activity against Gram-positive and Gram-negative bacterial strains when encapsulating 9-AA or KS. The cytocompatibility study indicated negligible to tolerable toxicity for the drug-loaded hydrogel, and the cell viability for the blank hydrogel was 92.5%, suggesting its suitability for biomedical applications.

Summary: Infectious wounds pose significant challenges in clinical practice and developing new antibiotics has become increasingly difficult. In this study, a K31-PGLa hydrogel was designed and synthesized, which demonstrated synergistic effects with commercial antibiotics against drug-resistant bacteria by down-regulating efflux pump synthesis genes. Furthermore, the photopolymerized K31-PGLa/PEGDA hydrogels effectively inhibited the growth of drug-resistant bacteria and promoted skin wound closure in mice.

Summary: Thermosensitive hydrogels have potential applications as fire extinguishing agents, but their slow response rate and wettability limitations need to be addressed. In this study, a thermosensitive porous system was synthesized by adding Na2CO3/CH3COOH as a foaming agent into a mixture of HPMC/PEG/CS. Different concentrations of the system were obtained by diluting the concentrate with water. The systems with a concentration greater than 15 wt% exhibited outstanding thermosensitivity and coagulability. The 20 wt% system showed the best spreadability and wettability on wood surfaces, and had a significant decrease in adhesive force and surface-free energy.

Summary: This study investigates the hydrolytic stability of chondroitin sulfate (CS) and hyaluronic acid (HA) methacrylate (MA) hydrogels. It was found that hydrogels made with glycidyl methacrylate-derivatized CS (CSGMA) degraded in a pH-dependent manner, while HA methacrylate (HAMA) hydrogels remained stable. The absence of hydrogen bonds in CS(G)MA may lead to higher chain flexibility and hydration, increasing its sensitivity to ester hydrolysis.

Summary: Porous chitosan materials were prepared as wound dressings by dissolving chitosan, inducing phase separation, forming a hydrogel, and drying through freeze-drying or supercritical CO(2) drying. The loaded drug, dexamethasone sodium phosphate, showed different release behavior from cryogels and aerogels based on the drying method, physicochemical properties, and pH of the release medium. Cryogels had higher loading efficiency and faster release compared to aerogels. The release kinetics were influenced by sample density and pH for aerogels, while cryogels were not significantly affected.

Summary: In the past decade, stimuli-responsive hydrogels have gained increasing attention in the field of tissue engineering and regenerative medicine. These smart hydrogels can replicate the physicochemical properties of the extracellular matrix and mimic dynamic processes that regulate cell behavior. By controlling the hydrogel properties or applying localized triggers, swelling-shrinking, shape-morphing, and patterns can be achieved to influence cell function in a spatiotemporally controlled manner. Additionally, stimuli-responsive hydrogels show great potential as bioinks for 4D bioprinting, enabling the fabrication of complex microstructures.
