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. The biosensors are coated with a bacteria-specific recognition layer containing particles of "phage," a virus that naturally recognizes bacteria, so that it's capable of detecting specific types of pathogenic bacteria.
