Identifying bioparticles comprises locating an individual particle on a substrate; irradiating a particle with a laser to form Raman spectrum; and comparing the formed Raman spectra with Raman spectra of different particles

摘要

Identifying bioparticles (I) comprises: locating an individual particle on a substrate (2) through irradiating at least an area of the substrate by means of light and measuring the light reflected by the particles; irradiating a particle with a laser and producing a localized Raman spectrum; and identifying (I) through comparison of the produced Raman spectrum with the Raman spectra produced by the majority of different particles. An independent claim is also included for a device (useful for carrying out the procedure) comprising a substrate (2), a detecting unit (3) (for locating individual particles on the substrate) and an identifying unit (4) (for identifying an individual particle by Raman spectroscopy).
