Researchers Develop Self-Cleaning Clothes

Ponca City, We Love You writes "Researchers at Monash University, in Australia, have found a process to coat natural fibers such as wool, silk, and hemp that will automatically remove food, grime, and even red-wine stains by coating their fibers with titanium dioxide nanocrystals, which break down food and dirt in sunlight. Titanium dioxide is a strong photocatalyst and in the presence of ultraviolet light and water vapor, it forms hydroxyl radicals, which oxidize, or decompose, organic matter. "These nanocrystals cannot decompose wool and are harmless to skin," says organic chemist and nanomaterials researcher Walid Daoud. Titanium dioxide can also destroy pathogens such as bacteria in the presence of sunlight by breaking down the cell walls of the microorganisms making self-cleaning fabrics especially useful in hospitals and other medical settings."

    Yes, but it reacts to the UV light...so all you have to do is replace your normal closet bulb with a bright UV lamp and then hang your clothes up for the night with the light on!

    Not only that, but your skin is crawling with "good" bacteria and how does it know the difference between the "bad" bacteria to break down and the "good" bacteria on your skin?

    More important than that, what happens to my skin when it gets oxidized?

    That crossed my mind, but I didn't want to veer off course.
