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

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
