Robotic white blood cells swim through the circulatory system of the human body, ingesting and destroying pathogenic critters such as harmful bacteria, viruses, etc. Each robot is about 3 to 3.5 microns in size, and built of nanoscale components. This size ensures that the robots will not get stuck while passing through the capillaries. The exact technical specifications on how these nanorobots will locate each pathogen, move/navigate toward them, and ingest them, is being researched by engineers. Once the pathogens are inside the nanorobots they are chopped to bits, the pieces reduced to non-toxic status by special enzymes, and the remains ejected out of an irising door. This is a variation of the Microbivores, created by Robert Freitas.
