In a major medical development, scientists have created a hybrid micro-robot that is only 10 microns wide — equivalent to the size of a single human cell. "In addition, the micro-robot has an improved ability to identify and capture a single cell, without the need for tagging, for local testing or retrieval and transport to an external instrument. Following this demonstration, the team is now working to put it to the test in vivo, with the hope that it will soon be used in a variety of medical research
