Can a door handle keep you healthy?
That depends on what’s on it. Most are teeming with bacteria: staph, E. coli, Enterococcus and sometimes even Salmonella. That stuff can make you sick.
Doors in the Reed, Prischak, Burke and Junker buildings on campus are now coated with something different: Agion silver, an antimicrobial compound that doctors put on catheters and heart valves. Moisture – in this case, the sweat and oils on a person’s hand – activates the silver ions, which bind to the bacteria’s cell walls. The cells die, and the surface is cleaner.
