Oh yeah, we have DNA robots.

Scientists have just created small machine-like organisms out of DNA that can perform simple tasks. Read more about it here.

“These new construction projects bring researchers a step closer to a time when, at least in theory, scientists might be able to build test-tube factories that churn out self-assembling computers, rare chemical compounds or autonomous medical robots able to cruise the human bloodstream.”

“They combined a programmable DNA track and a squad of mobile robotic walkers with a set of independently controlled molecular forklifts that can deliver parts on command. The result was a functioning nano-factory”

Immortality, anyone?
