摘要

高q窃窃廊谐振器，如芯片上的二氧化硅微球或微环体，已成功用于光学生物传感器[1]。由于具有较高的有效相互作用长度和较小的模体积，共振频率易受折射率(RI)变化的影响。特别是，有报道观察到单个病毒吸附引起的反应性波长偏移[2]。

Dispersive single particle sensing with μs time resolution using toroidal microresonators

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].
