Abstract

Polymer powered! A polymerization reaction has been used to power the first micromotor outside biological systems. The motor employs a form of Grubbs' catalyst asymmetrically bound to gold-silica Janus microspheres (see picture). These motors show increased diffusion of up to 70% when placed in solutions of the monomer. The motors also exhibit chemotaxis when placed in a monomer gradient.
