Students Design Self-Sanitizing Door Handle to Help Prevent Contagious Illnesses
Public door handles are often teeming with harmful bacteria, particularly in places like restrooms. That’s why University of Hong Kong graduates Sum Ming Wong and Kin Pong Li have designed a self-sanitizing door handle that uses UV light to kill germs. The designers were motivated to create a solution to unsanitary public surfaces after the devastating acute respiratory syndrome (SARS) outbreak between November 2002 and July 2003 in southern China.
