Abstract
Optically trapped specimens (typically nanoparticles having diameters between 1 and 50 nm) are excited with an optical beam so as to induce vibrations in the specimens. A trapping optical beam and the excitation optical beam can produce vibrations based on a difference frequency based on the trapping optical beam and the excitation optical beam. Scattered optical radiation as a function of modulation frequency can be recorded and used to identify or characterize the specimen.
