A surface plasmon resonance biosensor for angular and wavelength operation

This paper presents a surface plasmon resonance (SPR) sensor system based on a polymer prism chip. The device allows operation in both, the angular (AIM) and wavelength (WIM) interrogation modes. The basic mathematical formulation for both operating modes is discussed. Experimental sensogrammes obtained for both modes with the same polymer prism chip, are presented and compared. The results illustrate the feasibility of the proposed solution.
