"Artificial Bacterial Flagella (ABFs) are helical microrobots that can be remotely controlled using magnetic fields, mimicking the propulsive motion of bacteria E. Coli. In this image you can see the trajectory of an ABF (16 micrometers in length) and the dynamics of the nanoparticles flowing around it. An Artificial Bacterial Flagellum could be used to improve the tissue penetration of nanoparticles in tumor tissue by pumping them out of vessels and through diffusive tumor environments."
