Redesign of Computer Keyboards for Hospital and Consumer Use

Materials and Methods CNT growth is performed on prototype keyboard keys of 1.5x1.5 cm silicon wafers using a thermal chemical vapor deposition process. Our design was compared to four common keyboards currently on the market: a standard Mac computer keyboard, medical-grade waterproof keyboard, silver-coated antibacterial keyboard, and a plastic antimicrobial keyboard skin. Samples were analyzed using standard MRSA biofilm testing procedures and scanning electron microscopy.
