Abstract

A touch screen display that includes a touch screen user interface having a plurality of layers that includes a top surface layer. The display includes a coating composition coating the top surface layer. The coating composition includes metal-modified cerium oxide nanoparticles (mCNPs) having a predominantly 3+ cerium surface charge and in a range of about 3-30 nm in size and in an amount that is in a range of about 1 weight percentage of a mixture having a binder and the mCNPs and m is an antimicrobial promoting metal that is non-ionizing. The touch screen display is incorporated into various machines or electronic devices. The coating composition forms a self-disinfecting surface that is optically transparent.
