Easily scalable high speed magnetic micropropellers

In this work the fabrication and low Reynolds number swimming performance of a single helical turn micropropeller with easily scalable and reproducible geometry is described. The propeller is designed to explore recently revealed routes to optimize chiral magnetic microswimmers regarding high speed propulsion and maneuverability. This is achieved by velocity evaluation of micropropellers of varying size at different magnetic field rotation frequencies, and assessed with respect to the current state-of-the-art of magnetic microhelix propulsion.
