Metal NCs combat bacteria by releasing metal ions and inducing intracellular ROS generation. a Agar diffusion assay of zone inhibition by GSH-Ag+-R NCs, GSH-Ag0-R NCs, and ampicillin. b Schematic of possible antimicrobial mechanisms of GSH-Ag+-R NCs and GSH-Ag0-R NCs.

Red indicates gene up-regulation, and green indicates gene down-regulation
