INDIANAPOLIS — IU researchers say they’ve developed a fabric treatment that can kill the coronavirus on contact. The treatment was originally developed for bacteria infections, but the process is showing promise in stopping the spread of COVID-19. When any bodily fluid comes into contact with the fabric, it emits an electrical charge. The charge is harmless to humans, but kills COVID-19. Dr. Chandan Sen originally developed this fabric-imprinting method seven years ago for hard-to-treat bacterial infections. The process has received federal approval, and a bioelectrical company in Arizona is developing the process for commercial applications for the wound-care market and over-the-counter applications.
