A team of scientists from University College London report that they have developed a tough new self-cleaning paint. In a paper published in this week’s issue of Science, the researchers say the paint, made from coated titanium dioxide nanoparticles, is not only extremely repellent to water, but won’t get ruined even if it’s scratched or exposed to oil. Because it is so hard-wearing, it could be used for a wide range of applications, from clothing to cars. Reached for comment, our Caturday correspondent Professor Kibble said, “Big deal. I haz been self-cleaning since I was a itty-bitty kitty. I iz also extreemly rezistant to water (see Fig. 1 above).”
