Small, beautiful and additive-free Nov 14, 2009
The National Research Council Canada (NRC) recently helped Olympus, a world leader in advanced optical microscopy and medical imaging, to design and commercialize a CARS (Coherent Anti-stokes Raman Scattering) microscope ... The new Olympus microscope is based on a femtosecond non-linear optical process called CARS, which stands for Coherent Anti-Stokes Raman Scattering. (EurekAlert! -- Business News)
Artful Science: Peering into Ancient Pigments Aug 11, 2009
The process a version of surface-enhanced resonance Raman scattering (SERRS) uses silver nanoparticles to absorb miniscule amounts of dye molecules. In doing so, it overcomes two key obstacles that had prevented the compounds from being studied in the past: The silver nanoparticles enhance the reading of the otherwise dilute dyes; they also prevent the otherwise fluorescent substances from reflecting too much light when a laser is shined on them.

Targeting Tumors Using Tiny Gold Particles May 5, 2009
After the particles are injected, they can be imaged using a technique known as Raman scattering ... Because of this surface-enhanced Raman scattering, very low concentrations of nanorods - to only a few parts per trillion in water [gf1]- can be detected. (Science Daily)
Factors Other Than Genes Could Cause Obesity Apr 15, 2009
The researchers used a specialized imaging method called coherent anti-Stokes Raman scattering, or CARS, combined with other techniques, including flow cytometry and fluorescence microscopy ... Fluorophore-labeled insulin (green) is visualized with fluorescence imaging, and fat is visualized with coherent anti-Stokes Raman scattering - or CARS - imaging (red/white). (Science Daily)
Hollow gold nanospheres show promise for biomedical and other applications Mar 23, 2009
Zhang has studied a wide range of metal nanostructures to optimize their properties for surface-enhanced Raman scattering (SERS). SERS is a powerful optical technique that can be used for sensitive detection of biological molecules and other applications. (EurekAlert!)
Excessive Dietary Fat Caused 300 Percent Increase in Metastasizing Tumor Cells In Animal Models Feb 27, 2009
The researchers then used an imaging method called coherent anti-Stokes Raman scattering, or CARS, to document how increasing lipids from fat intake induces changes to cancer cell membranes ... Here, lipid-rich cancer cells (the two round objects) attach to collagen fibrils, simultaneously visualized using coherent anti-Stokes Raman scattering and sum frequency generation imaging.
