Patent ID: 7771660

Claim:
A system for identifying an unknown biological particle in a sample medium, said system comprising: an Electrophoretic Quasi-elastic Light Scattering (EQELS) spectrometer comprising an EQELS controller configured to generate a EQELS spectrum for the biological particle in the sample medium, wherein said biological particle comprises a biological cell; an EQELS analyzer in communication with said EQELS spectrometer; a reference database in communication with said EQELS analyzer, said reference database comprising a plurality of spectra, each of said plurality of spectra corresponding to an EQELS spectrum for one of a plurality of different types of known biological cells; wherein said EQELS analyzer is configured to compare said EQELS spectrum for the unknown biological particle in the sample medium from said EQELS spectrometer with said plurality of spectra from said reference database and to identify the unknown biological particle in the sample medium from the comparison.
