Biosensor for direct detection of pathogens on fresh produce

A type of biosensor is recently developed using magnetostrictive particle (MSP) resonator as sensor platform and phage/antibody as bio-probe. The MSP sensors have following unique features: wireless, concentration and separation of the target species from the analytes and in-situ detection capability. The MSP sensors are very inexpensive and sensitive. All the advantages of the MSP sensors are demonstrated by the in-situ detection of pathogens in water and liquid food. To fully utilize the advantages of the MSP sensors, the direct detection of pathogens on the surface of fresh produce was demonstrated.
