Slippery toilet bowl treatment causes bacteria to slide right off

When entering public restrooms, it's hard not to dwell on what germs previous users have left behind in the toilet bowl. Imagine, instead, a self-cleaning system that doesn't require a brightly colored gel. Researchers reporting in ACS Applied Materials & Interfaces have developed a simple, transparent coating that makes surfaces like porcelain more water-repellent. They show how this surface treatment effectively prevents bacteria from sticking to the inside of a toilet bowl.
