Abstract Zwitterionic hydrogels have attracted intensive attentions for their exceptional hydration and anti‐fouling properties, while the exploration rational structural designs to achieve multi‐function superior anti‐freezing capability remains an ongoing mission. Herein, a new multi‐functional zwitterionic monomer (ACHPES) is designed developed from which novel are fabricated. The pyridinium‐sulfonate motif endows hydrogel with discoloration in both visible light fluorescence response pH stimulus, enabling unique multi‐channel information encryption highly sensitive Cu 2+ detection threshold of 0.64 ppm. design carbamate group fulfils high bonding capacity water, leading capability. As such, exhibit extremely low water freezing point −47.3 °C breaking elongation ≈500% at −20 °C. outstanding enables sensors electrolytes excellent operational performance temperatures. This innovative strategy offers avenue functionalization application icy temperature.

Hydrophilic gel coatings have emerged as a promising strategy for surface modification and functionalization of biomedical devices. Nevertheless, most existing suffer from significant limitations, such low adhesion strength to substrates, fragility, complex preparation process involved with toxic solvents. Herein, overcome these issues simultaneously, we proposed simple method fabricate hydrogel coating based on tetraethyl orthosilicate (TEOS) copolymer poly(2-hydroxyethyl methacrylate) segments. The solution TEOS the can be applied substrate surfaces through various techniques, including drop coating, dip brush so on. Covalent bonds formed in situ condensation reaction occurred between silanol (originated TEOS) hydroxyl groups (on polymer plasma-treated substrate), ensuring robust durability coating. Notably, by copolymerizing certain monomers, customized functions could realized, underscoring practical value strategy.

Wound healing in patients with diabetes is challenging because of chronic inflammation, inadequate vascularization, and susceptibility to infection. Current wound dressings often target specific stages lack comprehensive therapeutic approaches. This study introduces a novel approach using photodetachable sponge scaffold incorporating carbon nanotubes (CNTs), known for their high photothermal conversion efficiency, electrical conductivity, water absorption properties. The incorporated pyrrolidonecarboxylic acid zinc (PC1Z2), compound anti-inflammatory moisturizing properties, which was cross-linked within network CNTs decellularized dermal matrix. resulting shape-memory actively interfaces endogenous electric fields, facilitating signal transmission skin cells accelerating tissue repair. Upon exposure near-infrared (NIR) light, the PC1Z2 enhanced antibacterial efficacy (98 %) through conversion, promoting metabolism at site. Notably, absorbed exudates gradually released Zn2+, effectively reducing inflammation mice. In diabetic rat model, exudates, reduced accelerated granulation formation, angiogenesis, re-epithelialization. innovative dressing shows promise enhancing wounds.
