“…Studies have found that Ag-NPs with a size of 5-20 nm had greater antibacterial activities [2][3][4]. Currently, the widely recognized antibacterial mechanisms of Ag-NPs include disrupting the normal function of the cell wall [5], interacting with the lipid components of the cell membrane to impede its normal function [6][7][8][9][10], inducing ROS free radicals to damage the cell membrane [11][12][13], damaging the DNA structure and inhibiting its related functions [14][15][16], binding with sulfhydryl groups of enzyme proteins to make cell inactive, and so on [17,18]. Ag-NPs inhibits the characteristics of simple preparation, broad-spectrum antibacterial, strong sterilization, and less prone to emerge drug resistance, which prompted it to be used as an antibacterial agent added to ceramics [19], coatings [20], textiles [21], films [22,23], and other raw materials to fabricate antibacterial materials.…”
