I am hoping to build a small and cost-effective magnetic device that can be applied to the neck to measure the presence of a small amount of magnetite nanoparticles in the bloodstream (on the order of 0.0002 to 0.002 um^3). I've looked at using permanent magnets and Helmholtz coils; however, those tend to be very pricey and are more powerful than is necessary. Is there a more effective solution?
Magnetic engineering isn't my forte so I apologize if some of my terminology or conjectures are incorrect.
