A wireless immunosensor for the detection of Mycoplasma genitalium was fabricated by immobilizing polyclonal antibody onto the surface of a magnetostrictive strip. In response to a time-varying magnetic field, the immunosensor longitudinally vibrates at a resonance frequency, emitting magnetic flux that can be remotely detected by a pickup coil. No physical connections between the immunosensor and the detection system are required, facilitating wireless aseptic operation. The binding of M. genitalium to the immunosensor surface resulted in a de...
