Illustration of the advanced photocatalytic and photothermal antibacterial therapy by the photo-activated Cu₃SnS₄ NFs. The electrostatic interaction, the ROS mediated oxidative damage, and the photothermal inactivation play a synergistic role in Cu₃SnS₄ NFs mediated antibacterial effect, which leads to obvious cell membrane damage to both Gram-negative E. coli and Gram-positive MRSA strains. Additionally, the copper ions released from the Cu₃SnS₄ NFs facilitate the vascular endothelial growth factor (VEGF) expression, which contributes to the revascularization of wounds and acceleration of wound healing
