Reducing the swelling of tissue-adhesive hydrogels is crucial for maintaining stable tissue adhesion and inhibiting inflammation. However, reported strategies reducing always result in a simultaneous decrease adhesive strength hydrogel. Furthermore, once covalent bonds break currently hydrogels, they cannot be rebuilt, hydrogel loses its ability. In this work, nonswelling (named as "PAACP") possessing regenerable high synthesized by copolymerizing crosslinking poly(vinyl butyral) with acrylic acid, gelatin, chitosan-grafted N-acetyl-l-cysteine. The obtained PAACP reaches 211.4 kPa, which approximately ten times higher than that can reused multiple cycles. as-prepared shows great potential soft bioelectronics, muscle fatigue successfully monitored via electrode array strain sensor integrated on substrates. success these bioelectronics offers applicability long-term diagnosis muscle-related health conditions prosthetic manipulations.

Abstract Wet-tissue adhesives have long been attractive materials for realizing complicated biomedical functions. However, the hydration film on wet tissues can generate a boundary, forming hydrogen bonds with that weaken adhesive strength. Introducing black phosphorus (BP) is believed to enhance water absorption capacity of tape-type and effectively eliminate layers between tissue adhesive. This study reports composite patch integrated BP nanosheets (CPB) wet-tissue adhesion. The patch’s improved mechanical properties ensure its immediate robust adhesion tissues. Various bioapplications CPB are demonstrated, such as rapid hemostasis (within ~1-2 seconds), monitoring physical-activity prevention tumour-recurrence, all validated via in vivo studies. Given good practicability, histocompatibility biodegradability CPB, proposed patches hold significant promise wide range applications.
