Abstract

In this work, a multilayer magnetic biosensor (SiO2/CoFeSiB/Al2O3/Cr/Au) based on the giant magnetoimpedance (GMI) effect, is designed and fabricated by micro-electromechanical system (MEMS) technology. Co68. 15Fe4. 3Si12. 5B15 alloy ingot was prepared using vacuum arc remelting (VAR) furnace and then amorphous ribbon was produced using melt-spinning process. In order to develop the GMI biosensor, a micro-pattern was implicated on the ribbon on a SiO2 substrate using lithography technique with a meander structure containing 10 arms. Al2O3/Cr/Au layers were deposited on the patterned ribbon using RF-sputtering technique. Differential scanning calorimetry (DSC) and X-ray diffraction (XRD) were used to evaluate the thermal property and structure of the ribbon. The results showed that the structure of the ribbon is amorphous. Finally, magnetoimpedance evaluation of the sensor was done at frequency range of 1-12 MHz and magnetic field of 0-170 Oe. In the GMI experiment, Fe3O4 nanoparticles were used as sensing elements. Based on the results obtained, it was shown that the maximum GMI ratio was 67% for blank sensor and is reduced by about 13% for sensor with 0. 1 mg Fe3O4 at frequency of 9 MHz. Therefore, due to the significant sensitivity of fabricated sensor to iron-oxide nanoparticles, this sensor has potential to be used for bio-magnetic applications.
