Reflective boost

A new approach to carrying out Raman spectroscopy and fluorescence measurements has been developed by UK scientists. Their approach exploits the backscattering nature of Raman and reflects the laser light used in the technique back into the system so that they can increase sensitivity and reduce spectral acquisition times. Kevin Buckley, Neil Macleod, Anthony Parker, and Pavel Matousek of the STFC's Rutherford Appleton Laboratory, in Oxfordshire and Allen Goodship of the Royal National Orthopaedic Hospital in Stanmore, Middlesex, explain that their technique has potential applications in pharmaceutical research, forensic science and security screening, where mixed media samples are common.
