Smarter drugs: Raman IV
Date: Oct 1, 2013
Author: David Bradley
Surface-enhanced Raman scattering (SERS) is about to make computerized smart systems that deliver drugs to hospital patients intravenously that much safer. Smart IV systems can deliver precise volumes at a precise rate, but they lack a critical ingredient to ensuring that the patient is not inadvertently harmed: they cannot know what concentration of drug has been added to the system nor can then confirm that it is even the correct drug being delivered.

Lip sync: Raman raises brand awareness
Date: Sep 1, 2013
Author: David Bradley
Forensic scientists in the UK have demonstrated that Raman spectroscopy can be used to identify the specific brand of lipstick someone was wearing at a crime scene without removing the evidence from its bag and so avoid possible cross-contamination and ensuring a secure prosecution.

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.
