Sensor Detects Early-Stage Parkinson’s

An electrochemical sensor 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. The sensor rapidly indicates the level of the protein PARK7/DJ-1 in human blood and synthetic cerebrospinal fluid. The molecule is associated with Parkinson’s at levels below 40 μg/L.
