New active particle

Caption

Sketch of the new catalytic mechanism proposed in the present Nature Communications paper. The particle is made of titanium dioxide with a gold-coated hemisphere. Its motion is induced by external illumination. Under green light, the particle moves towards the gold cap, but when exposed to UV light, it reverses its direction of motion and moves in the opposite direction. (Source: UW Physics, M. Lisicki)
