We present a theoretical analysis of the response of whispering gallery modes for biosensing applications, studied numerically in microcylinders and semi-analytically in microspheres. The effect of single and multiple particles is calculated, simulating biological analytes of different sizes and polarizabilities attached to the microresonator surface. Besides whispering-gallery-mode frequency shifts, we find that also broadenings and splittings (from lifted rotational symmetry) appear due to particles attachment and/or the vicinity to a planar coupler. For a single analyte, both particle size and refractive index can be determined from the broadening and shift, opening the perspective to a new biosensing modality.
