Scientists have developed a pair of tweezers shrunk down to an astonishingly tiny scale. The group demonstrated that the nanotweezers, fabricated by means of the base-pairing properties of DNA, could be used to keep biological molecules spatially separated or to bring them together as chemical reactants, depending on the open or closed state of the tweezers.
