In this study, Fe40Ni38Mo4B18 amorphous ferromagnetic ribbon was used as a vibrating reed sensor to detect Fe3O4 magnetic nanoparticles. The sensor surface was not subjected to any treatment: the amorphous ribbon was used directly as a sensor. Nanoparticles with a diameter of 25 nm in ddH(2)O were dripped on the sensor surface at different rates. Different amounts of magnetic nanoparticles ranging from 1 to 12 mu g were dripped, and it was observed that the sensor resonance frequency decreased linearly with the mass of magnetic nanoparticles dripped. It was shown that 1 mu g MNP could be easily detected by the vibrating reed method.
