Figure 7From: Antibacterial activities of gold and silver nanoparticles against Escherichia coli and bacillus Calmette-GuérinSchematic representation of the interactions between NPs and bacterial cells. (A) Bacterial cells take up single citrate Au NPs or aggregations of Au NPs complexes. (B) PAH facilitates Au NPs uptake into bacterial cells followed by lysis. (C) Most of Ag NPs were trapped in cell walls.Back to article page
