Sensor platform detects dopamine in sweat; could be used for future treatment

Penn State’s Aida Ebrahimi and Maurico Terrones, RPI’s Humberto Terrones, and colleagues, have developed a highly sensitive, non-invasive wearable Dopamine sensor platform. The goal is the use of the technology to develop wearable sensors able to track and eventually treat conditions caused by too much (ie schizophrenia) or too little (ie Parkinson’s, depression) dopamine.

The low cost, flexible detector was achieved by doping a Molybdenum disulfide with Manganes, embedded in two-dimensional transition metal dichalcogenide.

Current dopamine monitoring methods are invasive and require specialized lab equipment. The researchers described the new method as “very simple and scalable.”
