Patent ID: 8088628

Claim:
A method for determining the identity of a plurality of molecules of interest in a sample comprising: determining a Stokes Raman shift for at least two known molecules of interest; exciting the sample in a resonance chamber, which chamber comprises a reflector and a partial reflector, with at least two light sources, wherein a predetermined distance between reflectors is a function of wave length corresponding to prominent peaks in the Raman spectra for the two known molecules of interest, thereby selectively inelastically scattering radiation from the sample; resonating the inelastically scattered radiation between the reflector and partial reflector to amplify the intensity of the inelastically scattered radiation; transmitting the amplified inelastically scattered radiation from the chamber; detecting the transmitted amplified inelastically scattered radiation; and determining whether the detected transmitted amplified inelastically scattered radiation corresponds to one of the two known molecules of interest.
