The present invention relates to a method for manufacturing magnetic nanoparticles having a multi-functional group, comprising a step for treating the surface of magnetic nanoparticles with a base; and a step for coating the magnetic nanoparticles, whose surface is treated, with a base and the multi-functional group with silane. According to the present invention, the magnetic nanoparticles having a multi-functional group has high dispersibility by applying a negative (-) charge to the surface of the particle treated with a base, and a base is not treated with silane-coating. Therefore, the present invention has an effect for maintaining dispersibility, increasing reactivity and stability, providing magnetic nanoparticles at a high yield rate, reducing costs, and mass-producing in a simple method. |
