First step toward electronic DNA sequencing: Translocation through graphene nanopores

Researchers have developed a new, carbon-based nanoscale platform to electrically detect single DNA molecules. Using electric fields, the tiny DNA strands are pushed through nanoscale-sized thin pores in a graphene nanopore platform that ultimately may be important for fast electronic sequencing of the four chemical bases of DNA based on their unique electrical signature.

A first for DNA translocation: graphene

Using electric fields, researchers at the University of Pennsylvania push tiny DNA strands through nanoscale-sized, atomically thin pores in a 2-D layer of carbon atoms. The sequencer, the first ...
