High performance biosensors for the detection of bacterial in various media have been developed using magnetostrictive/magnetoelastic resonators (MSRs). An MSR is a strip of magnetostrictive alloy coated with biological molecular recognition unit, such as antibody and phage. The sensor is based on the change in its resonant frequency. Therefore, it is critical to determine the resonant frequency of...
The new design of a piezoelectric diaphragm as a sensor platform is introduced. A pressure chamber is added through the packaging process. It is theoretically indicated that the sensitivity of a piezoelectric diaphragm with an introduced pressure difference between two sides is significantly higher than that without this pressure difference. The high sensitivity is also experimentally proven. The...
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...
This paper demonstrates the direct detection of Salmonella typhimurium on fresh tomatoes using multiple phage based magnetoelastic (ME) biosensors. In this investigation, the sample collection/preparation step that is necessary for current pathogen detection methods was eliminated. ME biosensors are wireless sensors and are composed of a ME resonator platform immobilized with E2 phage. The E2 phage...
