New microendoscope poised to advance our understanding of the brain — ScienceDaily

Researchers have demonstrated a new endoscope that uniquely combines photoacoustic and fluorescent imaging in a device about the thickness of a human hair. The device could one day provide new insights into the brain by enabling blood dynamics to be measured at the same time as neuronal activity.

“Combining these imaging modalities could improve our understanding of the brain’s structure and behavior in specific conditions such as after treatment with a targeted drug,” said research team leader Emmanuel Bossy from the CNRS/ Université Grenobe Alpes Laboratoire Interdisciplinaire de Physique. “The endoscope’s small size helps minimize damage to tissue when inserting it into the brains of small animals for imaging.”

In The Optical Society (OSA) journal Biomedical Optics Express, Bossy’s research team, in collaboration with Paul C. Beard’s team from University College London, describe their new multi-modality endoscope and show that it can acquire photoacoustic and fluorescent images of red
