A gold star for SERS

Date: Nov 1, 2008

Author: David Bradley

Scientists at the National Institute of Standards and Technology (NIST) in Gaithersburg, Maryland, are using surface-enhanced Raman spectroscopy (SERS) to test the properties of star-shaped gold nanoparticles. They have found that these particles have optical qualities that outshine the competition and could make them useful in chemical and biological sensing and imaging.

In vivo nonmelanoma skin cancer diagnosis using Raman microspectroscopy

Date: Oct 6, 2008

Author:

The capability of Raman microspectroscopy to provide differential diagnosis of basal cell carcinoma, squamous cell carcinoma, inflamed scar tissue, and normal tissue in vivo has been studied.

Sooty balloons

Date: Oct 1, 2008

Author: David Bradley

Nothing more sophisticated than a lump of graphite, a roll of sticky tape, and a wafer thin sliver of silica are needed to inflate ideas about nanochemistry. Raman spectroscopy and other techniques have been used to reveal the details of the DIY construction of a balloon-like membrane of graphene.

Hybrid SERS technology

Date: Sep 1, 2008

Author: David Bradley

Surface-Enhanced Raman Scattering (SERS) of silicon nanostructures coated with a gold-silver substrate can be used to detect DNA hybridisation for biomedical and medical diagnostics purposes, according to a new study by researchers in Singapore.

In situ chemical analysis of modern organic tattooing inks and pigments by micro-Raman spectroscopy

Date: Sep 1, 2008

Author:

A methodology was established using micro-Raman spectroscopy on an animal model to correctly identify the constituents of a selection of modern, organic tattoo inks in situ or post procedure, within the skin. This may serve as a preliminary tool prior to engaging in Q-switched laser removals to assess the risks of producing potentially hazardous compounds.

Absorbing work with heavy metal

Date: Aug 1, 2008

Author: David Bradley

Raman spectroscopy, Fourier transform infrared spectroscopy and scanning electron microscopy have been used to work out the adsorption mechanism of toxic heavy metals on to magnetic nanoparticles. The particles are being developed as a novel remediation material for metals such as the toxic hexavalent chromium.

Raman boost, on reflection

Date: Jul 1, 2008

Author: David Bradley

UK scientists have developed a new approach for enhancing fluorescence and Raman signals recorded from turbid media in a conventional backscattering geometry. The technique results in an enhanced signal and allows the use of shorter acquisition times.

Passive signal enhancement in spatially offset Raman spectroscopy

Date: Jun 2, 2008

Author:

Signals in Spatially Offset Raman Spectroscopy (SORS) have been enhanced using a dielectric bandpass filter, leading to the enhancement of both the surface and subsurface Raman layer signal improving the signal-to-noise ratio of Raman spectra from the deep areas of samples.
