In remote locations in the developing world, detection and treatment of many infectious diseases requires cheap, easy-to-use diagnostic tests. To help meet the need, Brazilian researchers have developed a simple electrical sensor to detect antibodies for a pathogen in blood. Now they have shown that their biosensor can distinguish between mice infected with two human pathogens that have confounded other diagnostic systems (Anal. Chem., DOI: 10.1021/ac101920t).
