Life's ancient cooker
Date: Aug 1, 2009
Author: David Bradley
Raman spectroscopy has shown that organic material may have been 'cooked' in rocky mounds known as stromatolites that have been dated to 3.45 billion years ago.

Selectively deposited silver coatings on gold-capped silicon nanowires for SERS
Date: Jul 3, 2009
Author:
Gold caps on silicon nanowires have been selectively coated with silver by autometallography (electroless deposition) and the different morphologies achieved by changing the conditions of silver deposition were studied by SERS experiments.

Systematic nano Raman
Date: Jul 1, 2009
Author: David Bradley
Scientists in Israel and the US have demonstrated systematic differences in the Raman spectra of individual molecules adsorbed on small as opposed to large nanoparticles. The discovery has the potential to open up a new approach to single molecule studies.

Biochemical correlation of Raman spectra of normal, benign and malignant breast tissues: A spectral deconvolution study
Date: Jun 1, 2009
Author:
Spectral features and biochemical changes in normal, fibroadenoma and infiltrating ductal carcinoma of breast tissues measured using Raman spectra have been correlated using spectroscopic models developed earlier.

ELISA meet SERRS
Date: May 1, 2009
Author: David Bradley
Surface-enhanced resonance Raman scattering could be used to quickly spot the telltale signs of prostate cancer at the molecular level, according to a British team. This is the first use of a well-known ELISA colorimetric substrate as a SERRS marker.
