In yet another display of ingenious application, 3D printing has been utilized to develop reactive nano-sized fish. Researchers at the University of California, San Diego, have combined their unique 3D printing technology (microscale continuous optical printing) with robotics to create fish-shaped microrobots that “swim around efficiently in liquids, are chemically powered by hydrogen peroxide and magnetically controlled. What exactly are the capabilities of these multipurpose synthetics? When inserted into liquids, the microfish swim with attached nanoparticles in a manner that reacts accordingly to the environment that they are placed in. As a result, these microfish have the potential to institute an improved, directed system of medicine delivery. Furthermore, the developers have demonstrated that the microfish can be used as “detoxification systems and toxic sensors”.
