Abstract
A method of separating magnetic nanoparticles is described. The method comprises placing the magnetic nanoparticles in a periodic magnetic field. The periodic magnetic field varies between a first magnetic field strength and a second magnetic field strength that is higher than the first magnetic field strength. The nanoparticles may be superparamagnetic iron oxide nanoparticles.

A method of separating magnetic nanoparticles, the method comprising the step of placing the magnetic nanoparticles in a periodic magnetic field, wherein the periodic magnetic field varies between a first magnetic field strength and a second magnetic field strength that is higher than the first magnetic field strength, and
- further comprising the step of applying a flowing fluid to the magnetic nanoparticles subsequent to the step of placing the magnetic nanoparticles in a periodic magnetic field, and
- further comprising the step of capturing fractionated layers of magnetic nanoparticles that are released during the applying step.
A method of separating magnetic nanoparticles, the method comprising the step of placing the magnetic nanoparticles in a periodic magnetic field,
- wherein the periodic magnetic field varies between a first magnetic field strength and a second magnetic field strength that is higher than the first magnetic field strength,
- wherein the periodic magnetic field is present without flowing fluid, and
- further comprising the step of applying a flowing fluid to the magnetic nanoparticles after the step of placing the magnetic nanoparticles in a periodic magnetic field, and
- further comprising the step of capturing fractionated layers of magnetic nanoparticles that are released during the applying step.
