Synthetic Bio-Bots Take Their First Steps

Swimming like spermatozoa, researchers and engineers at the University of Illinois breathed life into a synthetic bio-bot that self-propels through the contraction of cultured heart cells known as cardiomyocytes. Modeled after single-celled organisms, these bio-bots consist of a long flagella-like tail made up of flexible polymer, alongside a short head by its end that is…
