Figure 1From: Size-dependent antimicrobial properties of sugar-encapsulated gold nanoparticles synthesized by a green methodEffect of different sizes of dextrose-encapsulated GNPs on the growth of E. coli . Growth analysis curves were measured by monitoring the optical density (OD) at 600 nm, and the E. coli was treated with dGNPs of sizes: 25 ± 5; 60 ± 5. and 120 ± 5 nm at different concentrations (NPs/mL).Back to article page
