Paper Abstract

Surface Plasmons Resonance (SPR) architectures involving multi-wavelength interrogation is an attractive alternative for droplet biosensing. In this work, we address two detection formats experimentally investigated by our research group. The first one involves an angular scanning combining one near-IR and one visible light probes. It enables to increase the number of parameters for numerical fitting, which improves the precision of measurement. The second concept involves the SPR Coupler and Disperser sensor principle, where the spectrum analysis is performed on each detector pixel using the same diffraction grating that is employed for the optical coupling of the incident light with the surface plasmons.
