Abstract

A biosensor includes a substrate with a receptive material layer of radiation-absorbing member (RAM)-tagged biomolecules disposed thereon. The receptive material is specific for an analyte of interest. A pattern of active and deactivated areas of the receptive material are defined in the receptive material layer by a masking process wherein areas are exposed through a mask with a light source to induce deactivation.
