PG - 14-29 LID - 10.1016/j.bioactmat.2024.03.011 [doi] AB - Multi-drug resistant bacterial infections pose a significant threat to human health. Thus, the development of effective bactericidal strategies is a pressing concern. In this study, a ternary heterostructure (Zn-CN/P-GO/BiS) comprised of Zn-doped graphite phase carbon nitride (g-C(3)N(4)), phosphorous-doped graphene oxide (GO) and bismuth sulphide (Bi(2)S(3)) is constructed for efficiently treating methicillin-resistant Staphylococcus aureus (MRSA)-infected wound. Zn doping-induced defect sites in g-C(3)N(4) results in a reduced band gap (DeltaE) and a smaller energy gap (DeltaE(ST)) between the singlet state S(1) and triplet state T(1), which favours two-photon excitation and accelerates electron transfer. Furthermore, the formation of an internal electric field at the ternary heterogeneous interface optimizes the charge transfer pathway, inhibits the recombination of electron-hole pairs, improves the photodynamic effect of g-C(3)N(4), and enhances its catalytic performance. Therefore, the Zn-CN/P-GO/BiS significantly augments the production of reactive oxygen species and heat under 808 nm NIR (0.67 W cm(-2)) irradiation, leading to the elimination of 99.60% +/- 0.07% MRSA within 20 min. Additionally, the release of essential trace elements (Zn and P) promotes wound healing by activating hypoxia-inducible factor-1 (HIF-1) and peroxisome proliferator-activated receptors (PPAR) signaling pathways. This work provides unique insight into the rapid antibacterial applications of trace element doping and two-photon excitation. CI - (c) 2024 The Authors.
