“the reason Bachelet and his colleagues' call their creations robots (and not just inert shapes) is that they perform actions given the right conditions. The nanobots themselves are cylindrical clamshells on flexible DNA hinges. Locked with twin DNA double helixes at the front, they carry a molecular payload, like a cancer drug, inside.
The DNA locks are engineered to react only with specific molecules or proteins on the surfaces of cancer cells. If present, the locks bind to these molecules, the clam shell opens, and the nanobot’s payload is delivered. This allows the nanobots to release drugs only near cancer cells, sparing the body’s population of otherwise healthy cells”
this is cool
