What they say about it

These devices, dubbed “DNA nanorobots,” are short hexagonal tubes made of interwoven DNA that can open along their length like a clamshell. At one end is a DNA “hinge,” and at the other, a pair of twisted DNA fragments that act as “latches” to hold the device shut. Inside the nanorobot, scientists can enclose molecules of almost any substance, essentially turning it into a molecular “delivery truck” that can transport medication to specific cells in the body.

How they say it works

Wyss Institute scientists have developed a drug-delivering nanorobot that looks like an open-ended barrel. The exterior surface of the device is programmed to recognize a target on a cell surface; the drug payload is secured with anchor strands to the interior. Double-stranded DNA latches ensure that the robot unlocks only in the presence of a molecular key expressed by the target cells. That opens the device, enabling the payload to attack only the designated cells. Source
