Nanostructures for Medical Diagnostics
(Hindawi Publishing Corporation;, 2011-10-19)
Nanotechnology is the art of manipulating materials on atomic or molecular scales especially to build nanoscale structures and devices. The field is expanding quickly, and a lot of work is ongoing in the design, characterization, ...
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 ...
