Reusable colour-changing sticky labels that act as a cheap and easy way to check the activity of photocatalysis-based self-cleaning glass have been designed by scientists in the UK.
Interest in self-cleaning technologies, including semiconductor photocatalysis (SPC), has been on the increase since the commercialisation of self-cleaning glass by Pilkington in 2001. However, SPC, a process by which light activation of a surface coating, usually titanium dioxide, facilitates the breakdown of organic dirt, is difficult to measure as most coatings are invisible to the eye.
