Researchers at north carolina State University have developed a nanocoating that can kill or inactivate most viruses and bacteria when exposed to visible light.

Early tests have shown that the coating kills 99.9 percent of influenza viruses and 99.99 percent of vaccinia virus, which causes rash, fever, head and body aches, according to azonano.com.

Prototypes will be used in performance trials targeting hospital areas including waiting rooms. The company is also developing a room air purifier that incorporates its nano-coated filter technology.

"We have many exciting opportunities to use these proprietary coatings to stop infection before it causes disease and death," says Tom Roberg, chief executive officer of LaamScience, the firm granted the license for the NC State patent. (photo influenza-pandemic.com)
