A nano-sensor for better detection of Mad Cow Disease agent

In an advance in food safety, researchers in New York are reporting development of a nano-sized sensor that detects record low levels of the deadly prion proteins that cause Mad Cow Disease and other so-called prion diseases. The sensor, which detects binding of prion proteins by detecting frequency changes of a micromechanical oscillator, could lead to a reliable blood test for prion diseases in both animals and humans, the researchers say. Their study is scheduled for the April 1 issue of ACS’ Analytical Chemistry.
