Grand challenges in surface enhanced optical spectroscopies

13 Sep 2011

Professor Duncan Graham

Take a look at Analyst Editorial Board member Duncan Graham’s contribution to our ongoing theme on Grand Challenges, which is included as part of Issue 19.

There remain several challenges to overcome in order to achieve widespread clinical use of surface enhanced techniques. In this review, Iain Larmour and Duncan Graham consider the substrates employed to achieve enhancement before reviewing each enhanced optical technique in detail; surface plasmon resonance, localised surface plasmon resonance, surface enhanced fluorescence, surface enhanced infrared absorption spectroscopy and surface enhanced (resonance) Raman spectroscopy.

Surface enhancement can provide improved detection sensitivity in a range of optical spectroscopies.

Read this comprehensive review on surface enhanced optical spectroscopies and their application to bioanalysis by Analyst Editorial Board member Duncan Graham and his colleague Iain Larmour. They consider the “grand challenges” that need to be overcome before widespread clinical use of surface enhanced techniques can be achieved.

The review will be free until the 6th September.

Detecting chemical and physical changes in thick tissue with X-ray excited luminescent sensors

21 Jun 2011

Scanning XEOL provides new capabilities for chemical analysis in tissue

The benefits of non-invasive biomedical imaging techniques in studying disease are obvious but developing sensors which can measure chemical concentrations around and on implants is challenging. This is because optical imaging through tissue results in light scattering and in turn, images with poor resolution. Jeffrey Anker and colleagues use a narrow scanning X-ray beam to excite luminescence from X-ray scintillators in this hybrid technique for high-resolution imaging of local optial absorption through tissue. The scintillators serve as light sources with spectra and intensity that depend on local absorption.
