An international team of scientists from the CNR-IFN, Politecnico di Milano, the University of Pisa, the Graphene Center of Cambridge (UK) and the Catalan Institute of Nanoscience and Nanotechnology (ICN2, Barcelona) has shown that the relaxation time of graphene charge carriers can be significantly modified by applying an external electrical field.

After light absorption, graphene's photoexcited charge carriers cool down to the initial equilibrium state in a few picoseconds, corresponding to a millionth of a millionth of a second. The remarkable speed of this relaxation process makes graphene particularly promising for a number of technological applications, including light detectors, sources and modulators.

Cambridge Raman Imaging (CRI) has announced it was selected to coordinate a project that received a €3.3 million grant in the European Innovation Council’s (EIC) Transition call.

The project, called CHARM, aims to develop a medical device based on high-speed, low-cost Raman digital imaging technology and artificial intelligence to transform cancer diagnosis and treatment. The technology will analyze the molecular composition of patient tissue samples to distinguish cancerous from healthy cells without the need for chemical staining.
