Thermo Fisher Scientific will host a series of free informative seminars on routine spectroscopy in the analytical laboratory. This seminar will explain the range of spectroscopic techniques currently available for use in the quality control or analytical laboratory. The essential theory of Infra-Red, Near-Infra-Red, Raman and UV spectroscopy will be covered, together with how to select the best technique for a given process or application. The seminar is aimed at scientists and analysts looking to commission, expand or replace spectroscopic analytical capabilities in their laboratory.
June 2, 2009 – Hemel Hempstead, UK
June 3, 2009 – Leeds, UK
June 4, 2009 – Edinburgh, UK
Attendance is free of charge. For registration visit:

A team of researchers led by Vadim Backman, professor of biomedical engineering of the Northwestern University, has developed a way to examine cell biopsies and detect never before seen signs of early-stage pancreatic cancer, according to a new paper published online by the OSA journal Optics Letters. The new technique, called „partial wave spectroscopic microscopy“ detects fluctuations in the cells‘ refractive index (an optical property that measure how cells bend light passing through them). These fluctuations are influenced by nanoscopic changes to the cells‘ interior architecture that often occur much earlier than the changes pathologists can detect under their microscopes. The more architectural disorder there is inside the cell, the more the refractive index fluctuates. The researchers showed that by quantifying these fluctuations, partial wave microscopy could identify cancer cells even in cases where they had not been detected by pathologists. Now, the partial wave spectroscopic microscopy has to prove effective in double-blind clinical trails.
