Polymer-Protected Sub-2-nm-Nanogap Fabrication for Biological Sensing in Near-Physiological Conditions
2009
Abstract
Polymer-protected sub-2-nm nanogaps that are fabricated via a novel electrical stressing approach exhibit substantial ionic-current reduction in near-physiological conditions. These devices enable direct DNA detection in aqueous solution by utilizing assembly of oligonucleotide-modified gold nanoparticles to the nanogap.
