Abstract:
The device and method disclosed herein concern detecting, identifying, and or quantifying analytes, such as nucleic acids, with high resolution and fast response times using surface enhanced coherent anti-Stokes Raman spectroscopy. In certain embodiments of the invention, a small number molecular sample of the analyte (210) such as a nucleotide, passes through a microfluidic channel, microchannel, or nanochannel (185) and sample cell (175) that contains Raman-active surfaces, and is detected by surface enhanced, coherent anti-Stokes Raman spectroscopy (SECARS). Other embodiments of the invention concern an apparatus for analyte detection.

Abstract:
Spectroscopic analysis systems and methods for analyzing samples are disclosed. An analysis system may contain an electromagnetic radiation source to provide radiation, a spectroscopic analysis chamber to perform a coherent Raman spectroscopy (e.g., stimulated Raman or coherent anti-Stokes Raman spectroscopy), and a radiation detector to detect radiation based on the spectroscopy. The chamber may have a resonant cavity to contain a sample for analysis, at least one window to the cavity to transmit the first radiation into the cavity and to transmit a second radiation out, a plurality of reflectors affixed to a housing of the cavity to reflect radiation of a predetermined frequency, the plurality of reflectors separated by a distance that is sufficient to resonate the radiation. The spectroscopic analysis system may be coupled with a nucleic acid sequencing system to receive a single nucleic acid derivative in solution and identify the derivative to sequence the nucleic acid.
