Abstract
We proposed a simple microfluidic device that enabled anisotropic absorption of detoxified S. typhimurium bacteria to each microcubic so that the particles can swim toward desirable direction by chemotaxis of the bacteria. The speed of the “bacteria-based microrobot” was ~5 um/sec which is faster than any prior demonstrations, leading to an effective drug delivery system.
