A team at Auburn University, Alabama has developed a real-time biosensing system to detect pathogenic bacteria such as salmonella. The research is described in the American Institute of Physics’ Journal of Applied Physics. According to a statement, what sets this biosensing system apart from traditional detection methods is a design that involves using a magnetoelastic biosensor — a low-cost, wireless acoustic wave sensor platform — combined with a surface-scanning coil detector.
