Abstract

We present four refractometric sensing platforms based on whispering gallery mode (WGM) modulated fluorescence spectra from active microsphere or capillary microresonators and scattered surface plasmon (SP) spectra from rough thin metal coatings and metal nanoparticles in waveguide and fibre dip configurations, respectively. Redshifts of the detected spectra upon increasing sample refractive index are demonstrated for each platform; label-free bio-sensing is also demonstrated.
