摘要
The detection method can include: exciting at least one fluorescent microsphere floating in said solution under test by exposing it to excitation light; measuring a fluorescence spectrum of said at least one fluorescent microsphere, said fluorescence spectrum comprising multiple whispering gallery modes; obtaining a set of predetermined fluorescence spectra corresponding to those of microspheres having varying external refractive index and varying radius, identifying a matching fluorescence spectrum of the set which more closely matches the measured fluorescence spectrum; comparing the matching fluorescence spectrum of the set to the measured fluorescence spectrum.
