The substance is made out of coated titanium dioxide nanoparticles . Any drop of moisture that touches it turns into a ball and rolls away . As it rolls off the surface it carries dust , dirt and germs with it . The breakthrough was made by researchers at University College London . It was inspired by the way birds keep birds afloat and plumage clean .
