DNA nano-robots specifically target cancer cells

An interesting and quite promising research came out recently and it has a pretty appealing topic name: DNA robots!

Basically, the nano-robot is a specially assembled DNA 'origami' with the tubular shape that can attach therapeutic molecules inside the tube (e.g. antibodies). It also has an outside lock (made of a double helix DNA) that keeps the tubular structure closed and is sensitive to the special molecules on the target cells' surface. Such nano-robot can specifically target the desired cell type, attach to these cells and deliver an antibody load to them.
