A team of researchers from Delft University of Technology (The Netherlands) announces a new type of nanopore devices that may significantly impact the way we screen DNA molecules, for example to read off their sequence. In a paper entitled 'DNA Translocation through Graphene Nanopores' (published online in Nano Letters), they report a novel technique to fabricate tiny holes in a layer of graphene and they managed to detect the motion of individual DNA molecules that travel through such a hole.
