Hybridising Raman
Date: Jun 1, 2007
Author: David Bradley
Dutch researchers have overcome the traditional incompatibility of Raman microscopy with fluorescence microscopy by exploiting the optical properties of semiconductor fluorescent quantum dots (QDs). They have now used their hybrid Raman fluorescence spectral imaging approach in single-cell microscopy applications.

Nanomechanics of single keratin fibres: A Raman study of the alpha-helix-beta-sheet transition and the effect of water
Date: May 1, 2007
Author:
The use of micro-Raman spectroscopy, through chemical-bond, nano-scale probes, allows the changes in conformations, chain orientation, breakage of disulfide bonds and the increase of intra- and inter-chain distances during the application of stress to be distinguished.

Raman and the "lead" in your pencil
Date: Apr 1, 2007
Author: David Bradley
Graphene recently hit the headlines as a futuristic molecular material from which almost atomic scale transistors might be carved. Interest has thus been piqued in studying all things graphitic. Now, an international team has turned the Raman spotlight on graphene and its chemical cousins to figure out a bit more about why these materials display their unique properties.

Fashionable flares
Date: Mar 1, 2007
Author: David Bradley
A newly studied group of catalysts could provide an environmentally beneficial answer to the problem of wasting natural gas by flaring at oil well sites, according to a study published in the March 7 issue of Journal of the American Chemical Society. Raman spectroscopy provides key information for the potential clean up operation.

Singling out molecules with Raman
Date: Feb 1, 2007
Author: David Bradley
A new approach to amplifying Raman signals has allowed Swiss chemists to characterise single molecules. The technique can address a 10 nanometre square substrate and quickly provide localisation and structural information, which will be of increasing importance to scientists and technologists working at the nanoscale.
