Microheater platform for selective detachment of DNA
(American Institute of Physics;, 2012-08-30)
Despite deoxyribonucleic acid (DNA)’s well-known temperature sensitivity, not much work has been reported on leveraging temperature to manipulate the interaction of DNA with surfaces. This paper describes a microheater ...
Electrical detection of single-base DNA mutation using functionalized nanoparticles
(Copyright American Physical Society,, 2009-08-17)
We report an electrical scheme to detect specific DNA. Engineered hairpin probe DNA are immobilized on a silicon chip between gold nanoelectrodes. Hybridization of target DNA to the hairpin melts the stem nucleotides. Gold ...
A mesoscale model of DNA interaction with functionalized nanopore
(Copyright American Physical Society,, 2009-11-30)
Direct current electrical characterization of ds-DNA in nanogap junctions
(Copyright American Institute of Physics;, 2005-04-05)
Measurements of DNA conductivity, hybridization, and melting using electronic means can have wide applications in molecular electronics and biological sensors. We have fabricated nanogap break-junctions by electromigration ...
