Graphene oxide (GO) is a promising platform to realize immobilization matrices for plasmonic biosensors. Here, we discuss various aspect of the deposition of GO thin films, their optical properties, and the influence of GO linking layers on biosensing sensitivity. Using spectroscopic ellipsometry, we obtain dielectric functions of thin GO films deposited by spray-coating in the visible and near-infrared ranges. In addition, we demonstrate that the optimization of GO linking layers may sufficiently increase the sensitivity of SPR biosensing.
