Abstract: (3378 Views)
Graphene nanopore is a promising device in the field of nanopore DNA sequencing due to its sub-1-nm thickness and good mechanical/electrical properties. Using ionic current in this device was the main driving force for the third generation DNA sequencing devices. Reading the DNA's transverse conductance was another innovative idea in these devices. To achieve single-base resolution these devices need low translocation speed. In this paper, we investigate dynamic properties of a double-stranded DNA (dsDNA), 5'CGCGAATTCGCG3', molecule with an external voltage drop in graphene nanopore with effect of static electric field parallel to the graphene nano ribbon using molecular dynamics simulation. DNA translocation speed calculated under different conditions and the results show the potential of the method to control the translocation speed experimentally in near future with surface plasmons propagating in the graphene.
