One in the eye for Raman
Date: Jun 1, 2008
Author: David Bradley
A simpler, gentler eye test based on Raman spectroscopy could spot ocular infection and other problems without irritating patients, although they may be required to yawn during the procedure.

Micro-Raman spectroscopy of pigments contained in different calcium carbonate polymorphs from freshwater cultured pearls
Date: May 5, 2008
Author:
Organic pigment molecules in the calcium carbonate polymorph vaterite regions of freshwater cultured pearls were analysed by resonance and near-resonance micro-Raman spectroscopy and compared with their aragonitic counterparts.

Boning up with Raman
Date: May 1, 2008
Author: David Bradley
A study to assess the biocompatibility and how well a new form of coated titanium implant can spur on bone growth has been carried out using a range of techniques including Raman spectroscopy, microcomputer tomography, scanning electron microscopy, atomic force microscopy, and energy dispersive X-ray analysis.

Phosphate and amide III mapping in sialoliths with Raman microspectroscopy
Date: Apr 7, 2008
Author:
The mechanism of sialolith formation was studied by analyzing the precise distribution of phosphate (an inorganic substance) and amide III (an organic substance) in sialoliths by using Raman microspectroscopy.

Micro-Raman characterizations of Pompei's mortars
Date: Mar 3, 2008
Author:
Micro-Raman spectroscopy was used to study mortars from different points of the wall in the The House of the Wedding of Hercules in Pompei. Remarkable differences between ancient and modern mortars were found, allowing a discrimination in historical buildings which had several prioids of restoration.

Trans fats and cancer cells
Date: Mar 1, 2008
Author: David Bradley
Raman spectroscopy has helped a Japanese team reveal the presence of high concentrations of the trans form of unsaturated lipids in cancer cells. The discovery could lead to new insights into how different cancers progress and potentially novel therapies.

Raman spectroscopy of ion-irradiated astrophysically relevant materials
Date: Feb 21, 2008
Author:
Solid objects in space such as interstellar grains and comets are continuously exposed to energetic processes, such as cosmic ion irradiation, that influence their evolution. In this paper the authors present an experimental study, carried out by Raman spectroscopy, of the effects induced by ion irradiation on frozen ices and refractory materials. This paper was published in a Special Proceedings Issue of the Journal of Raman Spectroscopy marking the 20th Italian Conference on Raman Spectroscopy.

Raman spectroscopy differentiates malignant tumors from normal breast tissue and detects early neoplastic changes
Date: Feb 4, 2008
Author:
Near-infrared Raman spectroscopy shows potential in differentiating human breast tumors from normal tissue and can detect early neoplastic changes prior to definite morphologic alteration in a mouse model.

Genetic magnification
Date: Feb 1, 2008
Author: David Bradley
The sequencing of DNA or proteins is a complex procedure requiring sophisticated analytical techniques. However, a new approach to this almost ubiquitous, yet onerous, task, based on Raman spectroscopy, could make things much simpler and potentially less expensive.
