A sensor for identifying at least one particle by means of Raman-spectroscopy, comprising an optical trapping system for the at least one particle, including a laser-beam source, acting further as a Raman excitation source for the at least one particle, and a Raman-spectrometer for measuring the spectrally modified light scattered by the at least one particle and for identifying same, wherein the optical trapping system comprises a photonic crystal directly linked with the laser-beam source, which photonic crystal has multiple cavities at predetermined positions, and wherein the laser-beam source in use resonantly excites one or more predetermined electromagnetic modes of the cavities at said positions for trapping and Raman-exciting the at least one particle.
