Fig: DNA translocating through a graphene nano gap device
I will describe our lab's latest efforts in realizing a graphene nanogap device that may be used for sequencing individual DNA molecules. The technique is based on reading the base sequence of a single DNA molecule using a graphene nanogap to read the DNA’s transverse conductance. Because graphene is a single atom thick, single-base resolution of the conductance is readily obtained. The nonlinear current-voltage characteristic is used to determine the base type independent of nanogap-width variations that cause the current to change by 5 orders of magnitude. The expected sequencing error rate is 0% up to a nanogap width of 1.6 nm.
