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.
