Light cleans clothes

Researchers at the Royal Melbourne Institute of Technology have developed a nanocoating for fabrics which could soon put an end to having to wash clothes. Instead, it will be enough to simply put the clothes out in the sunshine for six minutes. The nanocoating consists of copper and silver. When it comes into contact with light, so-called hot electrons are released that dissolve organic material such as dirt. The researchers are now trying to find a method of manufacturing this nanocoating industrially and integrating it into textiles.
