Abstract: A method comprises exposing the surface of an optical microcavity characterized by at least one resonance frequency to a sample such that a single particle or molecule from the sample adsorbs onto the surface of the microcavity; evanescently coupling a probe laser beam into the microcavity, the wavelength of the probe laser beam substantially matching the at least one resonance frequency; illuminating the surface of the microcavity with a free space pump light beam and moving the focal spot of the free space pump light beam such that the focal spot substantially overlaps with the single particle/molecule; and detecting light from the probe laser beam. The wavelength of the free space pump light beam generates sufficient heat via energy absorbed by the single particle/molecule to induce a shift in the at least one resonance frequency, thereby providing a change in an optical characteristic of the detected light.
