Avi-pG-pC on Mica (DNA)

A reliable method of deposition of aligned individual dsDNA molecules on mica, silicon, and micro/nanofabricated circuits is presented. Complexes of biotinylated double stranded poly (dG)–poly(dC) DNA with avidin were prepared and deposited on mica and silicon surfaces in the absence of Mg2+ ions.
