NANOMAGDYE: The marker
• Phosphonate coupling agent stabilizes pH at 4.7 -> blood.• Simple experiment for biocompatibility• Synthesis with microbubbles -> ultrasound
contranst agent
NANOMAGDYE: The probe• Magnetic and optical sensor built together• Fluxset sensor: soft magnetic core, two coils: driving and pickup coil
• No intrinsic magnetic field: excited with a third coil: excitation coil• Nanoparticles need very strong excitation: differential excitation
Measurements on low velocities
Measurements on hand movement speed
Conclusion• At low velocities there are no significant distorting effects• At higher velocities the distorting effects are at most 10-15% of the maximum
amplitude
• The probe is completely capable of the measurements it was designed to do
• Simulation of the measurements• Algorithm for signal source localization
