Abstract Background Diabetic wounds present significant challenges, specifically in terms of bacterial infection and delayed healing. Therefore, it is crucial to address local issues promote accelerated wound In this investigation, we utilized electrospinning fabricate microgel/nanofiber membranes encapsulating MXene-encapsulated microgels chitosan/gelatin polymers. Results The film dressing facilitates programmed photothermal therapy (PPT) mild (MPTT) under near-infrared (NIR), showcasing swift extensive antibacterial biofilm-disrupting capabilities. PPT effect achieves prompt sterilization within 5 min at 52 °C disperses mature biofilm 10 min. Concurrently, by adjusting the NIR power induce heating (42 °C), stimulates fibroblast proliferation migration, significantly enhancing vascularization. Moreover, vivo experimentation successfully validates dressing, underscoring its immense potential addressing intricacies diabetic wounds. Conclusions MXene microgel-loaded nanofiber employs temperature-coordinated therapy, effectively amalgamating advantageous features high-temperature low-temperature promotion It exhibits rapid, broad-spectrum capabilities, exceptional biocompatibility, noteworthy effects on promoting cell These results affirm efficacy our highlighting challenge struggling heal due infection.

Abstract In this study, a tough chitosan‐gelatin‐polyacrylamide‐Fe 3+ (CGPA‐Fe ) hydrogel with triple‐network structure is successfully synthesized using photoinitiated free‐radical polymerization. The designed to achieve high‐strength, low‐swelling material suitable for biomedical applications. Experimental results demonstrate that the CGPA‐Fe exhibits excellent mechanical properties, compressive stress of 5.29 MPa and modulus 1.27 under 80% strain. Furthermore, shows outstanding fatigue resistance, retaining nearly 100% its peak after 10 compression cycles. It also displays remarkable self‐recovery capabilities, an energy dissipation recovery rate exceeding 85% 60‐s rest period. Regarding swelling behavior, demonstrates stability, further highlighting potential structural summary, represents promising candidate materials.
