Xenobots
Xenobots, named after the African clawed frog, are self-healing microbots that are designed and programmed by a computer and built from the ground up using biological cells. A xenobot is a biological machine under 1 millimeter wide, small enough to travel inside human bodies.They are made of skin cells and heart cells, stem cells harvested from frog embryos. University of Vermont & Tufts University scientists have created this living machine that one day might safely deliver drugs inside the human body—and pave the way for understanding how to form organs for regenerative medicine. Xenobots can walk and swim, survive for weeks without food and work together in groups, can heal on their own and keep working.
