SiO@AuAg/PDA hybrid nanospheres with photo-thermally enhanced synergistic antibacterial and catalytic activity.

Wastewater discharged from industrial, agricultural and livestock production contains a large number of harmful bacteria and organic pollutants, which usually cause serious harm to human health. Therefore, it is urgent to find a "one-stone-two-birds" strategy with good antimicrobial and pollutant degradation activity for treating waste water. In this paper, SiO@AuAg/Polydopamine (SiO@AuAg/PDA) core/shell nanospheres, which possessed synergistic "Ag-release-photothermal" antibacterial and catalytic behaviors, have been successfully prepared a simple redox polymerization method.

Size-dependent magnetomechanically enhanced photothermal antibacterial effect of FeO@Au/PDA nanodurian.

The global health crisis of bacterial resistance to antibiotics requires innovative antibacterial strategies. One promising solution is the exploitation of multifunctional nanoplatforms based on non-resistant antibacterial mechanisms. This work reports a novel FeO@Au/polydopamine (PDA) nanodurian with excellent photothermal-magnetomechanic synergistic antibacterial effects.
