NM11–Numerical Investigation of a Plasmonic Biosensor on Flexible Substrate

Surface plasmon resonance (SPR) based sensors are state of the art in bio-sensing. Here we numerically inspect a device that can induce SPR on the opposite side of planar metal films. The evanescent field of SPR can detect wide of refractive index with linear sensitivity. This device modeled on bendable PDMS substrate can launch SPR modes with perpendicularly incident light which enhances the robustness and practical feasibility of the whole system.
