pH-Responsive nanoplatform synergistic gas/photothermal therapy to eliminate biofilms in poly(l-lactic acid) scaffolds

The constructed ZnS–Ti 3 C 2 /PLLA scaffolds were able to release H 2 S gas to disrupt biofilm and further remove bacteria through photothermal. In addition, the Zn 2+ released from the composite scaffolds could promote osteogenic differentiation of BMSCs.
