TL;DR: Doping of amorphous titania with Ag resulted in an anti-MRSA effect without exposure to UV radiation, and in the Ag-doped crystalline anatase samples, the size of Ag primary nanocrystallites increased, which led to the decrease in the surface concentration of Ag and detriment anti- MRSA activity.
