Figure 6.
Effects of silver nanoparticles (Ag-NPs) on the proliferation of Leishmania tropica promastigotes in the dark and under ultraviolet (UV) light in different incubation periods (I, parasites in control group in the dark; II, parasites exposed to Ag-NPs in the dark; III, parasites in control group exposed to UV light; IV, parasites exposed to Ag-NPs under UV light). Ag-NPs had significant effects on Leishmania parasites in the experiment groups compared with the control groups. The biggest effect was observed in the experiment group exposed to Ag-NPs and UV light.
