Irregularly shaped wounds cause severe chronic infections, which have attracted worldwide attention due to their high prevalence and poor treatment outcomes. In this study, we designed a new composite functional dressing consisting of traditional Chinese herb carbonized plant powder (CPP) and a polyacrylic acid (PAA)/polyethylenimine (PEI) gel. The rapid gelation of the dressing within 6-8 s allowed the gel to be firmly attached to an irregularly shaped wound surface and avoided powder detachment.

- Skin injuries from exercise can form irregular shapes and become infected due to bacteria trapped in the wounds.
- A new hydrogel made of polyvinyl alcohol and polyhydroxylated fullerenes was developed, which can penetrate these irregular wounds and demonstrated a 240% increase in healing efficiency while also effectively killing bacteria.
- This hydrogel also has excellent electrical conductivity for real-time motion monitoring and can self-heal quickly, making it useful for both treating wounds and monitoring recovery.
