Nanotech enhancement: Gold rush
Date: Aug 1, 2013
Author: David Bradley
It is possible to tune gold nanoparticles with peptides for surface-enhanced Raman spectroscopy (SERS) in such a way as to side step the problematic stages inherent to other approaches to nanoplasmonic structures for analyte detection, according to Italian researchers.

Portable infection: SERS detection
Date: Jul 1, 2013
Author: David Bradley
The optical technique of surface-enhanced Raman scattering (SERS) has been used to detect signs of infection in tissue samples before patients even show symptoms of viral disease. The system could be further developed into a portable lab-on-a-chip (LoC) devices for use in the clinic with potential for applications in the developing world.

Algorithmic Raman: Improved breast diagnostics
Date: Jun 1, 2013
Author: David Bradley
A newly developed, single-step algorithm for processing Raman spectra can reveal the presence of microcalcifications in breast tissue that are often associated with breast cancer lesions and so improve the precision of diagnosis of the disease itself at the early stages without multiple biopsies of suspicious lumps.

TNT, meet graphene: Explosive sensor
Date: May 1, 2013
Author: David Bradley
Another chemical pie in which graphene has its lacy carbon fingers is in the form of a sensitive and selective detection system for the common explosive trinitrotoluene (TNT). Silver nanoparticles functionalised with p-aminothiophenol (PATP) and supported on graphene sheets allow the straightforward surface-ehanced Raman spectroscopic SERS) detection of the explosive.

Journal Highlight: Graphene: A platform for surface-enhanced Raman spectroscopy
Date: Apr 29, 2013
Author: spectroscopyNOW
The multi-role of graphene played in SERS is overviewed, including as a Raman probe, a substrate, an additive, and a building block for a flat surface for SERS.

Journal Highlight: Trace level detection and identification of nitro-based explosives by surface-enhanced Raman spectroscopy
Date: Apr 1, 2013
Author: spectroscopyNOW
Surface-enhanced Raman spectroscopy has been used to detect and identify traces of pentaerythritol tetranitrate (PETN), ethylene glycol dinitrate (EGDN), cyclotrimethylene-trinitramine (RDX) and trinitrotoluene (TNT) using commercially available substrates.
