Published in the journal Science Robotics, the nanorobot is built from a single DNA molecule and has a hand-like design with four fingers with three joints each, allowing precise manipulation of objects at the microscopic level.
NanoGripper works on the principle of DNA origami, which folds a long strand of DNA into a complex three-dimensional shape. The structure contains DNA aptamers that bind to specific targets, such as viral particles, triggering the movement of the “fingers.”
In tests, the NanoGripper paired with a photonic crystal sensor detected viral particles within 30 minutes with sensitivity comparable to traditional molecular tools. It has also demonstrated the ability to prevent viral infection by blocking the interaction of viral proteins with cellular receptors.
