METHOD OF COUPLING BONDING AGENTS TO A SUBSTRATE SURFACE

摘要

The present invention relates to a method of coupling multiple binding agents to respective areas of a substrate by hydrodynamic addressing, using two laminar fluid flows that flow together in the same direction over the substrate surface with an interface to each other to successively couple the binding agents to the substrate areas, wherein each successive coupling of a binding agent to a surface area is followed or preceded by selective deactivation or activation of a selected surface area according to a defined protocol. The invention also relates to the use of such binding agent-coupled substrate surface for analytical purposes.
