Abstract

Artificial active nano- and microparticles driven by light are of special interest since their propulsion can easily be controlled via the illumination. Recently, we have established a propulsion mechanism based on asymmetric light refraction caused by a refractive-index gradient. We will introduce into this new approach based on two-photon polymerization of the active particles, and demonstrate active propulsion under illumination as well as pattern formation in colloidal suspensions of these active particles controlled by light.
