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 ...
Thermal stability of ohmic contacts between Ti and Se-passivated n-type Si(001)
The thermal stability of the interface between Ti and Se-passivated n-type Si(001) is investigated. As-deposited Ti contacts show ohmic characteristics. After annealing at temperatures from 200 °C to 480 °C in air, the ...
