Self-Referencing Integrated Biosensor Based on Surface Plasmon Resonance Mediated Luminescence

Abstract

A sensing device for characterizing a substance by modifying modes of resonance of surface plasmons is described. The sensing device comprises: a photo-emitting substrate layer for generating a luminescence signal; a dielectric adaptive layer applied onto the photo-emitting substrate layer; and a sensing layer applied onto the dielectric adaptive layer, the sensing layer having a sensing surface for coupling with the substance to be characterized. The luminescence signal generates surface plasmons having modes of resonance at the interface of the sensing layer and the substance to be characterized. The substance to be characterized, when coupled to the sensing layer, characteristically modifies the modes of resonance of the surface plasmons.
