(a) Effect of Ag-NPs on the survival of S. aureus for different concentrations of Ag-NPs (12.5, 25, 50, and 100 μg/ml) under normal light condition. (b) Effect of laser irradiation at 410 nm and photoirradiation of Ag-NPs on the survival of S. aureus for different exposure times (1, 3, 5, and 10 min) and concentrations of Ag-NPs (12.5, 25, and 50 μg/ml).
