21_14i/2011Nanoelectrodes: Enhanced DNA Sequencing Performance Through Edge-Hydrogenation of Graphene Electrodes (Adv. Funct. Mater. 14/2011)

Nanoelectrodes fabricated from graphene could potentially achieve the crucial single-nucleobase resolution required for novel nanopore-based approaches at DNA sequencing. The aspect of hydrogenated graphene edges has been explored by Ralph H. Scheicher, Ming Liu, and co-workers, on page 2674, through molecular-dynamics simulations and electronic-transport calculations. The temporary formation of hydrogen bonds with DNA is shown to entail higher conductivity and a reduced statistical signal distribution.
