Dual elemental doping activated signaling pathway of angiogenesis and defective heterojunction engineering for effective therapy of MRSA-infected wounds.

ABSTRACT: 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-C₃N₄), phosphorous-doped graphene oxide (GO) and bismuth sulphide (Bi₂S₃) is constructed for efficiently treating methicillin-resistant Staphylococcus aureus (MRSA)-infected wound. Zn doping-induced defect sites in g-C₃N₄ results in a reduced band gap (ΔE) and a smaller energy gap (ΔE_ST) between the singlet state S₁ and triplet state T₁, which favours two-photon excitation and accelerates electron
