An international team of researchers has developed a handheld, non-invasive device that can detect biomarkers for Alzheimer’s and Parkinson’s Diseases. The biosensor can also transmit the results wirelessly to a laptop or smartphone. The team tested the device on in vitro samples from patients and showed that it is as accurate as the state of the art method. Ultimately, researchers plan to test saliva and urine samples with the biosensor. The device could be modified to detect biomarkers for other conditions as well. The device relies on electrical rather than chemical detection, which researchers say is easier to implement and more accurate.
