Low-cost sensor detects early-stage Parkinson’s disease in biological samples

Researchers at the University of Campinas (UNICAMP) and the Federal University of São Carlos (UFSCar) in Brazil have developed an electrochemical sensor that detects Parkinson’s disease at different stages. The device was fabricated using an ordinary 3D printer and proved capable of early diagnosis, also serving as a model for the identification of other diseases, according to an article published in the journal Sensors and Actuators B: Chemical.
