Dysregulation of serotonin plays a role in many psychiatric disorders, including severe depression and anxiety. In the journal Angewandte Chemie International Edition, a research team has now introduced an implantable, electrochemical microsensor that makes it possible to study serotonin dynamics in the brain in real time. In contrast to previous sensors, these are not deactivated by deposition of serotonin oxidation products because the measurement occurs without current flow.
