In order to create these Xenobots, scientists extracted tissue from 24-hour-old frog embryo and assembled them into using computer models. These tiny blobs measure only 0.04 inches wide and can survive for several weeks at a time.
Xenobots can move independently and collectively and also heal their own wounds if get hurt. They have ability to sense their environment turning red when exposed to blue light. Scientists are hoping to use them in treatment as they can transport particular medicines to a specific part of the body when needed.
