Prussian blue nano-enzyme-assisted photodynamic therapy effectively eradicates MRSA infection in diabetic mouse skin wounds

In the constructed CPB-Ce6 NPs, Ce6 killed MRSA by generating 1 O 2 , CPB NPs used CAT activity to generate O 2 and alleviate hypoxia, and Ce6 used O 2 to enhance PDT. CPB-Ce6 NPs accelerated wound healing in diabetic mice infected with MRSA .
