Supermat Intl. develops three-dimensionally (3D) ordered nano-gels and nano-composites of polyacetylene (NPA) which characterized abnormally high intensity of resonant and non resonant Raman scattering. NPA can be prepare in the form of solutions, gels, films and plates and retains optical properties under high power laser irradiation.

NPA can be used as high intensity external and internal Raman labels and standards for quantitative Raman spectroscopy and its applications.


Raman spectroscopy is commonly used to analyze chemical structure of molecules and materials. It is successfully applied to a wide range systems in:

Material science
Solid state physics
Nanotechnology
Semiconductors and superconductors
Geology and mineralogy
Pharmaceutics
Biology
Medicine
Forensics

Raman spectroscopy enables remote characterization and real-time monitoring of industrial and biological processes, and provides fingerprint information by which molecules can be identified. It has extremely high potential for application in high technology for process measurements and quality control, and in medicine for biomedical issues such as early detection of cancer and rapid identification of pathogenic microorganisms.

However, most prospective industrial and bio-medical applications of Raman spectroscopy require quantitative measurements. The main obstacle for quantitative Raman spectroscopy is low efficiency of the Raman scattering process, which generally requires ~1 million incident photons to yield 1 Raman-scattered photon. Registration of Raman scattering spectra therefore requires high-powered laser beams and high signal amplification, which in turn leads to high intensity of background fluctuations and a low Raman scattering signal to noise ratio. A whole set of problems will need to be resolved to bring quantitative Raman spectroscopy to the market, chief among them being the lack of high intensity Raman labels and standards.

Raman spectra of NPA
NPA can be used in Raman spectroscopy as:

external standards for calibration of spectrometer wavelength, laser wavelength, laser intensity and relative Raman scattering signal intensity
external and internal standards and labels for quantitative Raman spectroscopy
internal sensors for correction and stabilization of Raman scattering signal against laser power- and background fluctuations.

NPA is highly effective as a reference material for qualitative Raman measurements employing laser excitation wavelengths of 488 nm, 514 nm, 532 nm, 647 nm, 785 nm, and 1064 nm.

Internal standards and labels will be produced in the form of solutions. Concentration of nanoparticles in solution and solvent content can be customized as needed. External standards, labels and sensors will be produced in the form of solutions, gels, films or plates in cells (ampoules, containers) of optical glass. Size and shape of cells will be optimized for specific parameters and optical scheme of Raman instrument.

High intensity Raman labels and standards will become commercially available in Dec 2007.

We are looking for funds and strategic partners to further along our development.

Supermat Intl. will shortly relocate from NY depending on the needs of the business.
