Scientists develop graphene 'tweezers' to grab molecules
US-based scientists have developed electronic "tweezers" using graphene, a 2D form of carbon, that can efficiently grab biomolecules floating in water. Graphene, being single atom thick, can trap nanoparticles using much lesser voltage than conventional methods that lack "sharpness". The team showed the tweezers could be used for trapping nano-diamond particles and even DNA molecules.
