Raman Spectroscopy News and Research

RSS

In Raman spectroscopy, a laser is used to irradiate a sample. Almost all of the light is scattered in an elastic manner, meaning no change in energy occurs. However, a small percentage of light is scattered in an inelastic manner, known as Raman scattering. This process was first observed by Indian scientist Sir Chandrashekhara Venkata Raman in 1928.

Two new techniques to identify dissolved cocaine in bottles of wine or rum

In two landmark studies published today in the journal Drug Testing and Analysis (DTA), UK and Swiss research teams reveal two techniques proven to identify dissolved cocaine in bottles of wine or rum. These tools will allow customs officials to quickly identify bottles being used to smuggle cocaine, without the need to open or disturb the container.

Portable laser devices to probe early signs of diseases

Portable devices that use a laser beam to probe bones, teeth, and other parts of the body for early signs of diseases like osteoporosis and tooth decay may seem like something out of science fiction. But those devices are moving closer to reality, according to an article in the current issue of Chemical & Engineering News (C&EN), ACS' weekly newsmagazine.

Researchers develop new application for improved detection of breast cancer cells

Single-walled nanotubes—cylinders of carbon about a nanometer in diameter—have been highly touted for potential applications such as ultrastrong fibers, electrical wires in molecular devices, or hydrogen storage components for fuel cells. Thanks to a new development by researchers at the National Institute of Standards and Technology (NIST) and five partners, you can add one more application to the list: detection and destruction of an aggressive form of breast cancer.
