A team comprising researchers from the Gloucestershire Royal Hospital, Strathclyde University and CLF have developed a new technique, SESORS (link opens in a new window), for non-invasive spectroscopy of translucent samples.The team demonstrated a unique deep imaging capability of SESORS by measuring signals of low level analytes from within a 50 mm-thick slab of biological tissue.
The method combines two Raman spectroscopic techniques, SERS (Surface Enhanced Raman Spectroscopy) and SORS (Spatially Offset Raman Spectroscopy). The record breaking penetration depth is an order of magnitude higher than that demonstrated previously with conventional SERS. The new technique could offer a valuable tool for future disease diagnosis (link opens in a new window).
