Distance magnetic nanoparticle
detections were investigated by using a magnetoelectric based magnetic sensor
with a long type bilayer Metglas/PZT laminate composite.
In homogeneous magnetic fields, the
sensor exhibits a sensitivity of 307.4 mV/Oe, which is possible for a detection
limit of 2.7 x 10(-7) emu.
This sensor can detect an amount of
0.31 mu g of the superparamagnetic Fe3O4-chitosan fluid at 2 mm height above
the sensor surface.
To detect a spot with magnetic
nanoparticles at a distance of about 7.6 mm, it should contain at least 50 mu g
of iron oxide.
This approach can develop the local
detection of magnetic nanoparticles at a depth of centimeters in the body
during clinical interventions.
