The Naval Research Lab has developed a compact instrument that uses 64 sensors, 200 μm in size, that are coated with either proteins or single-stranded DNA to capture 64 analytes of certain  biomolecules-as may be encountered in biological warfare, naturally occurring epidemics, human and veterinary medicine, or environmental testing.  The sensor work off of a phenomenon called giant magnetoresistance.   MORE
