Abstract
A biosensor for use in a surface plasmon resonance (SPR) System includes a transparent substrate layer, a thin metallic film on the substrate, and an ultrathin organic layer of a material which is polyanionic and adsorbs on the metallic film, and a layer of polylysine on this polyanionic material. In one embodiment, there is an outer layer on the polylysine which binds with a specific desired analyte.
