Design and operation of antimicrobial nanomotors. (a) Illustration of the Janus architecture of AuNR-SiO2-Cu7S4 nanomotors, highlighting their plasmon-enhanced photocatalytic activity and self-propulsion driven by thermophoresis under 1064Â nm light exposure. (b) NIR-II light triggers synchronized autonomous motion, along with combined photothermal and photocatalytic antibacterial actions, improving transdermal penetration and effectively combating infections caused by methicillin-resistant Staphylococcus aureus (MRSA).
