Abstract

See full text

The present invention relates to a method for preparing a nickel ferrite nanoparticle composite having an inverse spinel structure obtained using a polyol process, a nickel ferrite nanoparticle composite prepared by the method, and a method for selectively binding, separating or purifying a specific protein using the nickel ferrite nanoparticle composite. The method for preparing a magnetic nanoparticle composite according to the present invention includes a one-step hydrothermal synthesis process, and thereby the magnetic nanoparticle composite can be prepared in a simple and economic manner. Also, the nickel ferrite nanoparticles synthesized by the method of the present invention can be strongly magnetic, and also exist in the form of Ni2+ in which Ni binds to a specific protein, thereby preventing loss of separability caused by additional oxidation and repeated recycling of the nanoparticles.
