Impact of Optical Cavity on Refractive Index Sensitivity of Gold Nanohole Arrays
Refractive index sensing based on surface plasmon resonance (SPR) is a highly efficient label-free technique for biomolecular detection. The performance of this method is defined by the dielectric properties of a sensing layer and its structure. Nanohole arrays in thin metal films provide good refra...
