A new laser source for infrared chemical imaging: a promising tool for early cancer diagnostic
Sébastien Février, researcher at XLIM (CNRS/Université de Limoges), and his team demonstrated that a bench-top, optical fibre-based laser source can be used to perform infrared spectromicroscopy with a precision rivaling, and in some regards even surpassing, that of experiments at large-scale synchrotron facilities. Synchrotrons are accelerator facilities that provide powerful infrared light used for analyzing the chemical content of biological tissues with micrometer scale resolution. This high precision chemical imaging technique enables an early diagnosis of pathologies such as cirrhosis and cancer. However, up to now, the very high cost of ownership and limited availability of synchrotron sources has hindered the deployment of chemical imaging technique in the hospital. Replacing the synchrotron with a compact laser source could unleash the potential of this technique and ease its implementation in the hospital, thus accelerating access to diagnosis and treatment.
