Swimming Nanobot To Deliver Drugs

nanobot cargo swimmer
Georgia Tech has developed a blood-swimming robot model that looks like a fish and can deliver drugs or build minute structures piece-by-piece. The 10-micron nanorobot uses material changes to move, like exposing hydrogels to electricity, heat, light or magnetism. An important thing to mention though is that the model is actually a scientifically viable design needing someone to build it.
