Abstract :
This paper presents a sensitivity study for a surface plasmon resonance (SPR) sensor system based on a polymer prism chip capable of operating both at angular and wavelength interrogation modes. This investigation aims at optimizing the manufacturing procedure for maximizing the the sensitivity and the detectivity of the sensor system. Given a selected operating point the sensor detectivity has been calculated allowing the direct comparison of achievable performance at both interrogation modes.
