a The structure and operation schematic of flexible wound dressing. In this system, PDMS-sealed flexible electronic superstratum includes UV-LEDs, temperature (T) sensor, a Bluetooth chip with immediate wireless signal delivery performance; UV-induced GS release hydrogel substratum was introduced for anti-infective therapy. (i-iii) Schematic diagram of working principle of theranostic dressing. (i) The wound temperature is measured in real time for offering high temperature warning caused by bacterial infection. (ii) switching on the UV-LEDs to activate the release of GS antibiotic. (iii) antibiotic release for bacterial removal, further reducing wound inflammation and wound temperature. b GS was modified to the PEG-based hydrogel via a UV-sensitive chemical bond. c GS release profiles under continuous (black line) and intermittent (red line, turn on 2 min /turn off 10 min for 5 circles) exposure to ultraviolet light.
