3D-printing microscopic fish: Team demonstrates novel method to build robots with complex shapes, functionalities

Nanoengineers at the University of California, San Diego used an innovative 3D printing technology they developed to manufacture multipurpose fish-shaped microrobots—called microfish—that swim around efficiently in liquids, are chemically powered by hydrogen peroxide and magnetically controlled. These proof-of-concept synthetic microfish will inspire a new generation of "smart" microrobots that have diverse capabilities such as detoxification, sensing and directed drug delivery,...
