Abstract:

Patterns of pre-formed hybridizable nucleic acid oligomers are formed upon a substrate. The substrate is coated with molecules such as aminosilanes, whose reactivity with nucleic acid molecules can be transformed by irradiation. The coated substrate exposed to patterned irradiation then contacted with pre-formed nucleic acid oligomers. The binding of the preformed nucleic acid oligomers to the coating molecules may be covalent or non-covalent for example ionic bonding or hydrogen bonding. If desired a heterobifunctional crosslinker may be employed before or after irradiation, with the coating to promote covalent binding of the nucleic add oligomers to the coating molecules. Also. the irradiation step may be performed with the assistance of a positive tone or negative tone photoresist.
