Abstract :
Summary form only given. We previously demonstrated an interferometric surface plasmon resonance (SPR) biosensor design based on measuring the differential phase between the s- and p-polarization. In this presentation, we report our recent results on the development of sensor arrays achieved by analyzing interferograms generated under SPR conditions. The measurement approach has the merits of performing highly paralleled two-dimensional detection at fixed angle of incidence. In addition, we also demonstrate further improvement of detection resolution (in the order of 10-8 RIU) by incorporating novel ideas in the design of the optical interferometer.
