​New graphene-based method could improve DNA sequencing 

A new graphene-based method could make for faster, cheaper and more accurate DNA sequencing, according to a group of Leiden scientists. The research team has received EUR 1.2 million through the Dutch Research Council (NWO) Open Technology program to develop their new method.

The new DNA sequencing method builds on a previous Leiden discovery in which the research groups of chemist Grégory Schneider and physicist Jan van Ruitenbeek got an electrical current to jump across two layers of graphene, each an atom thick. By bringing the two layers close together at a certain angle, they caused tunnelling to occur. This is a quantum mechanical phenomenon where electrons jump from one material to another despite there being no direct contact between the two.
