Researchers say their sensor can monitor levels of the neurotransmitter in real time, bringing at-home health management ‘closer to reality’

They said the patch – which uses microscopic needles to test fluid just beneath the skin – was painless and monitored dopamine levels in real time.
“The innovation opens up entirely new technological pathways for the continuous monitoring of neurotransmitters, making early screening for neurological diseases and smart, at-home health management closer to reality,” the scientists wrote in the August issue of peer-reviewed journal Biosensors and Bioelectronics.
Parkinson’s disease – which causes symptoms such as tremors and movement problems – is believed to be caused when the brain cannot produce enough dopamine because the nerve cells that make it stop working.
