cBASS Full Technology Demo Platform (IMAGE) Naval Research Laboratory Caption This portable magnetoresistive biosensor system utilizes an IC chip with an embedded giant magnetoresistance sensor array called the Bead ARray Counter (BARC). BARC detects paramagnetic microparticles that are used to label protein or DNA molecules of interest in a sandwich-based assay. The BARC chip is housed in an assay cartridge which contains an integrated fluid cell, microfludics bus and a PCMCIA connector to quickly interface with the compact Bead Array Sensor System (cBASS). cBASS includes a low power electromagnet, an automated fluidic system, and supporting electronics, all of which is controlled by a computer through a USB interface.
