Abstract
The method of preparing multifunctional magnetic-optical nanoparticles, includes: preparing magnetic nanoparticle clusters by mixing an oily phase containing magnetic nanoparticles and an aqueous phase containing a cationic surfactant; coating the magnetic nanoparticle clusters with a water-soluble polymer; and preparing multifunctional magnetic-optical nanoparticles by mixing a cluster solution containing magnetic nanoparticle clusters coated with the water-soluble polymer and a quantum dot solution containing quantum dot nanoparticles, wherein the solvent of the cluster solution has a higher polarity index than the solvent of the quantum dot solution.
