Formation of micro and nanoscale patterns of monolayer templates for position selective immobilization of oligonucleotide using ultraviolet and electron beam lithography
Formation of organosilane monolayer templates using ultraviolet and electron-beam (EB) lithography was investigated. The oligonucleotides were covalently immobilized with high selectivity only to the amino-monolayer modified regions locally formed on the template surfaces at micro and nanometer scale. By using EB lithography, patterned immobilization in nanometer scale, as small as 20nm, was achieved.
