Nanowire Detection of Prostate Cancer
Quoting directly: “[Ecole Polytechnique Federale de Lausanne (EPFL)] researchers have managed to get around this obstacle by inventing a new detection technique. The trick is to trap the molecules of interest by the blood sample and then detect them in a dry environment, where measurements won’t be disturbed by all the molecules. To do this, the researchers used a Memristor – a new electrical component that can “remember” all the electrical currents that pass through it. The device has been successfully tested on the biomarker for prostate cancer, known as the Prostate Specific Antigen (PSA).” The sensors enhanced sensitivity comes from passing a current through the silicon nanowire from both directions and recording where a voltage gap occurs.
