Magnetic GMI sensor for detection of biomolecules
- 1. National Institute of Research and Development for Technical Physics, 47 Mangeron Blvd. 700050 Iasi (Romania)
Description
A magnetic sensor based on the giant magnetoimpedance (GMI) effect for the detection of biomolecules was made with a CoFeSiB amorphous magnetic microwire as sensing element. Using soft ferromagnetic cobalt microparticles and field sensitivities of the impedance of about 2.5%/A m-1 in the very low field region (less than 200 A m-1) at frequencies close to 10 MHz, a highly sensitive response was measured, appropriate for the detection of low biomolecule concentrations
