Soft sensor tracks the neurochemical messengers dopamine and serotonin

Neurotransmitters have key roles in regulating the nervous system. To better understand these processes, researchers need tools to analyse neurotransmitter signalling in the organs of living animals. We have invented NeuroString, a soft sensor for monoamine neurotransmitters, which can be fitted to the brain or gut of animals without disturbing the organ’s natural functions.
