Medical nanorobots. Computer illustration of nanorobots at work in a human blood vessel. The vessel contains red blood cells (red discs) and white blood cells (transparent spheres). The robots at upper left have drills to clear away any debris or clots that are blocking blood flow. The nanorobot at lower centre is injecting a drug into a cancerous or infected cell. Each nanorobot is powered by two small propellers.
