Light-propelled anisotropic refractive microswimmers — •Matthias Rüschenbaum1, Elena Vinnemeier1, Jörg Imbrock1, and Cornelia Denz1,21Institute of Applied Physics, Münster, Germany — 2Physikalisch-Technische Bundesanstalt (PTB), Braunschweig, Germany

Self-propelled microswimmers offer a wide range of applications, for example in biomedicine or colloidal systems. Among the various drive mechanisms, light-propelled microswimmers offer many advantages such as high biocompatibility and precise control. In our approach, the refraction of light provides a directed propulsion for the particles. These particles have an asymmetric geometry and are several micrometers in size. In addition, chiral particle shapes ensure a rotating motion. The light-driven microswimmers are fabricated by direct laser writing using two-photon polymerization, which enables high versatility and accuracy. The laser light-induced movement is then evaluated and compared for the different particle shapes.

Keywords: Microswimmers; Two-photon polymerization; Light-propelled; Refractive index; Chirality
