Key Points

Researchers at the Federal University of So Carlos (UFSCar) and the University of Campinas (UNICAMP) in Brazil invented an electrochemical sensor that can identify Parkinson's disease at various stages...

The gadget was created using a standard 3D printer and showed early disease detection capabilities, serving as a model for the detection of other diseases, according to the study...

Specific antibodies for PARK7/DJ-1 were immobilized on the surface of the electrodes, and the sensor was used to detect the protein at three levels: 30 mg/L, 40 mg/L and 100 mg/L..

If onset of the disease is suspected, physical and behavioral symptoms have probably appeared, and the disease is probably already well-established," said Juliano Alves Bonacin, last author of the article and a professor in the Department of Inorganic Chemistry at IQ-UNICAMP...

We decided to design and produce a very simple device that was cheap and could be used for continual monitoring, with alerts for physicians and patients if there were alterations in the level of PARK7/DJ-1, which is especially useful when analyzed in conjunction with other biomarkers...
