Brilliant dye to probe the brain

To obtain very-high-resolution 3D images of the cerebral vascular system, a dye is used that fluoresces in the near infrared and can pass through the skin. The Lem-PHEA chromophore, a new product outclassing the best dyes, has been synthesized by a team from the Laboratoire de Chimie (CNRS / ENS de Lyon / Université Claude Bernard Lyon 1). Conducted in collaboration with researchers from the Institut des Neurosciences (Université Joseph Fourier - Grenoble / CEA / Inserm / CHU) and the Laboratoire Chimie et Interdisciplinarité: Synthèse, Analyse, Modélisation (CNRS / Université de Nantes), this work has been published online in the journal Chemical Science. It opens up significant prospects for better observing the brain and understanding how it works.
