Features

Touchscreen surface warfare—Physics and chemistry of antimicrobial behavior of ion-exchanged silver in glass

20

C. Kosik Williams, N.F. Borrelli, W. Senaratne, Y. Wei, and O. Petzold


   Glass composition, silver concentration, and ambient conditions control antimicrobial efficacy on ion-exchanged glass surfaces and could reduce bacteria population on glass touchscreens.
