Laser induced graphene sensor enables dopamine detection in tears
Researchers in Brazil have developed a low-cost, noninvasive sensor using laser-induced graphene to detect dopamine levels in human tears. This technology could provide a new method for monitoring neurological conditions like Parkinson's disease.
Why it matters
Noninvasive diagnostic tools can significantly improve patient compliance and early detection rates for chronic neurological disorders.
Researchers from Brazil's Federal University of Pelotas and Federal University of Rio Grande do Sul have developed a laser-induced graphene sensor that can detect dopamine with high sensitivity in tear fluid, pointing to a possible noninvasive route for monitoring neurological disorders.
