DNA Through Graphene Nanopores
Delft University of Technology announces a new type of nanopore devices that may significantly impact the way we screen DNA molecule
Researchers have developed a novel technique to fabricate tiny holes in a layer of graphene (a carbon layer with a thickness of only 1 atom), and were then able to slide a single molecule of DNA through a tiny nanoscale hole. The DNA moves base per base through the nanopore. With the atomically thin graphene nanopore, one in principle has the potential for reading off the DNA sequence, base per base.
In addition to sequencing, graphene nanopores could offer additional benefits, such as improving sensors for science and other applications.
