Abstract
High-Q whispering gallery resonators, such as silica microspheres or microtoroids on a chip, have been successfully employed as optical biosensors [1]. Due to a high effective interaction length and a small mode volume, the resonance frequency is susceptible to small variations of the refractive index (RI). In particular, the observation of reactive wavelength shifts resulting from the adsorption of single virus has been reported [2].
