Influence of chitosan (CS)–black phosphorus (BP)-based hydrogels in rat infected wound healing. (A) Schematic illustration of visible light sterilization that stimulates skin regeneration in the presence of CS/BP nanosheet-based hydrogel; (B) E. coli (left) and S. aureus (right) colony units in dark conditions and after PDT for 10 min under simulated sunlight. The control tissue culture plate (TCP) was compared with CS- and CS-BP-based hydrogels; (C) Healing effect in S. aureus-infected wounds after in vivo treatment under dark conditions (a) and simulated sunlight for 10 min at Days 0, 2, 4, 8 and 14 (b) (figure adapted with permission from [80].
