Figure 5From: Size-dependent antimicrobial properties of sugar-encapsulated gold nanoparticles synthesized by a green methodSpread plate assays of S. epidermidis after treatment with dGNPs at different concentrations. (A) Plate assay showing the number of viable cells recovered after the treatment of S. epidermidis without (control) or with dGNPs). (B) Graphs plotted for the number of S. epidermidis colonies recovered against the number of dGNPs.Back to article page
