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.

Raman spectroscopic study of the Mapungubwe oblates excavated in South Africa
Date: Jan 7, 2008
Author:
Oblate seed beads excavated on Mapungubwe hill, an Iron Age site in South Africa, were analysed with Raman microscopy and supportive techniques to determine the glass technology and pigments used to produce the beads.

Raman snuffs out Martian life
Date: Jan 1, 2008
Author: David Bradley
Analysis of a meteorite from the planet Mars may have laid to rest the possibility of finding life on the Red Planet. A comprehensive imaging study including confocal micro Raman spectroscopy has helped US researchers uncover the origin of organic molecules found in the meteorite and show that these carbon-containing compounds were produced by non-living processes.

Early cancer detection with Raman
Date: Dec 1, 2007
Author: David Bradley
Raman spectroscopy could become a new tool in the early detection of wayward cervical cells exposed to human papillomavirus (HPV) that may ultimately turn cancerous. The new approach to detecting neoplasia could avoid false positives and negatives and ultimately reduce cervical cancer rates, and save lives.
Read MoreMolecular characterization of reconstructed skin model by Raman microspectroscopy: Comparison with excised human skin
Date: Dec 1, 2007
Author:
Raman microspectroscopy is a rising and powerful nondestructive technique for studying skin that detects characteristic molecular vibrations. In this study, a spectral database was created to index the vibration peaks and bands of a well-known reconstructed epidermis model, the Episkin®, for comparison with native skin.
