摘要： A material comprising positively and negatively charged nanoparticles, wherein one of said nanoparticles contained a magnetically responsive element, are combined with a support molecule, which is a long natural or synthetic molecule or polymer to make a magnetic nanoparticle assembly. When the magnetic nanoparticle assembly is combined with cells, it will magnetize those cells. The magnetized cells can then be washed to remove the magnetic nanoparticle assembly and the magnetized cells manipulated in a magnetic field.

摘要： A ferrite magnet with salt includes 40 to 99.9 weight % of ferrite and 0.1 to 60 weight % of salt, wherein the salt has a melting point lower than a synthetic temperature of the ferrite, and the salt is melted to form a matrix between the ferrite particles, and a manufacturing thereof. The ferrite magnet with salt has advantages in terms of process conditions due to fast synthesis reaction at low temperatures compared to typical magnets, easily obtaining nano-sized particles having high crystallinity, preventing cohesion between particles and particle growth by molten salt, allowing sintering at temperatures lower than typical during the molding and sintering processes for producing a ferrite magnet with salt due to synthesized ferrite magnetic powder with salt thus preventing the deterioration of magnetic characteristics due to particle growth, and allowing alignment in the direction of magnetization easy axis to obtain higher magnetic characteristics.
