Biocompatibility of Ag-NPs in Vero cells. Vero cells were exposed to Ag-NPs for 24 hours (A), 48 hours (B), or 8 days (C) and the cell viability was determined using a standard MTS assay. The effects of the Ag-NPs on cellular viability are expressed as percent of control (untreated Vero cells) with error bars representing standard error of the mean (S.E.M.).
