Abstract:
A process for applying a spatially defined reagent area to a solid phase having an essentially continuous metal or metal oxide surface to form a solid phase matrix, comprising applying droplets of a liquid containing an absorptive binding reagent and at least one of a) different solid phase reactants and b) solid phase reactants at different concentrations to a solid phase having an essentially continuous metal or metal oxide surface for an adequate time period to enable formation of absorptive bonds between the binding reagent and to form a solid phase matrix, said matrix having at least one spacially defined reagent area thereon, wherein said at least one spacially defined reagent area contains at least one of a) different solid phase reactants and b) solid phase reactants at different concentrations.
