ScholarBank@NUS Repository. https://doi.org/10.1002/smll.200900938 | 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 (see image). | Source Title: | Small | URI: | http://scholarbank.nus.edu.sg/handle/10635/57089 | ISSN: | 16136810 | DOI: | 10.1002/smll.200900938 |
