The development of a new surface plasmon resonance (SPR) imaging biosensor is reported. The biosensor exploits the optical properties of a nano-structured gold-polymer chip, which allows for the coupling of the SPR with the incident light. The spectral characterization of the chip permits to analyze the plasmonic response to a refractive index change near its free surface. The nano-structured surface features are presented together with an exemplifying biological tests which demonstrate the multiplexing label-free detection capability of the proposed device.

Abstract

The development of a new surface plasmon resonance (SPR) imaging biosensor is reported. The biosensor exploits the optical properties of a nano-structured gold-polymer chip, which allows for the coupling of the SPR with the incident light. The spectral characterization of the chip permits to analyze the plasmonic response to a refractive index change near its free surface. The nano-structured surface features are presented together with an exemplifying biological tests which demonstrate the multiplexing label-free detection capability of the proposed device.

Applied Physics/Condensed Matter/Materials Science encompasses the resources of three related disciplines: Applied Physics, Condensed Matter Physics, and Materials Science. The applied physics resources are concerned with the applications of topics in condensed matter as well as optics, vacuum science, lasers, electronics, cryogenics, magnets and magnetism, acoustical physics and mechanics. The condensed matter physics resources are concerned with the study of the structure and the thermal, mechanical, electrical, magnetic and optical properties of condensed matter. They include superconductivity, surfaces, interfaces, thin films, dielectrics, ferroelectrics and semiconductors. The materials science resources are concerned with the physics and chemistry of materials and include ceramics, composites, alloys, metals and metallurgy, nanotechnology, nuclear materials, adhesion and adhesives. Resources dealing with polymeric materials are listed in the Organic Chemistry/Polymer Science category.
