Description

technical field [0001] The invention relates to a magnetic field control system. Background technique [0002] Due to their unique properties, magnetic nanomaterials have been widely used in modern society and have attracted more and more attention. Magnetic nanoparticles refer to nanoscale magnetic materials, such as Fe 3 o 4 , under the action of an external magnetic field, it is magnetic and can move toward the direction of the magnetic field and concentrate on the designated part. Using this feature, magnetic nanoparticles have a wide range of applications in biology and medicine. Whether the magnetic nanoparticles are used alone or combined with other biomolecules or functional materials as a magnetic carrier, the surface modification of the magnetic nanoparticles is required. Through surface modification, the magnetic nanoparticles can be transformed from the oil phase to the water phase, improving the Stability of nanoparticles in solution. The most widely used ma...
