Abstract

Light propelled micro-machines yield important advantages. While most other propulsion mechanisms require some kind of fuel in the surrounding medium, light acts as an external energy source which enables high spatio-temporal control. In our novel approach the actuation emerges from refraction of light on micro-machines with an asymmetric shape and refractive index profiles. The artificial micro-machines are fabricated by femtosecond laser lithography by two-photon polymerization which enables high precision and flexibility. We demonstrate and compare the propulsion of light propelled particles with different geometries and refractive index gradients.
