Abstract
A process for creating a two dimensional spacial distribution pattern of ferent thiolate molecules on a substrate by illuminating a surface of a self-assembled monolayer of a first thiolate compound in the presence of oxygen with high frequency electromagnetic radiation distributed according to a desired pattern, and subsequently immersing the illuminated substrate in a solution of a second thiolate compound so that molecules of the first thiolate compound in illuminated areas of the monolayer are exchanged for molecules of said second thiolate compound; and a patterned biomolecular composite formed of a substrate which forms a self-assembled thiolate monolayer when immersed in a solution of a thiolate forming compound, a thiolate monolayer deposited on the substrate and composed of patterned areas of first and second thiolate compounds, respectively, the first thiolate compound having an affinity for specifically or nonspecifically adsorbing a biological molecule, and the second thiolate compound having essentially no affinity for the biological molecule, and at least one biological material adsorbed in a corresponding pattern on the patterned areas of the first thiolate compound in the thiolate monolayer.
