Biobots

Once again, fact is stranger than fiction.  Engineers at the University of Illinois’ Micro and Nanotechnology Laboratory have used a 3-D printer to create a “walking” bio-bot made of hydrogel that takes power from beating rat heart cells.  As the cells pulse, a hydrogel leg propels the structure forward.  Developers believe this device has potential for in vitro drug screening and chemical analysis.  MORE
