Abstract
Official abstract text for this publication.
The present invention relates to a method of manufacturing a superparamagnetic nanocomposite and a superparamagnetic nanocomposite manufactured using the same, and more particularly to a method of manufacturing a superparamagnetic nanocomposite suitable for use in magnetic separation for the detection of a target biomaterial and a superparamagnetic nanocomposite manufactured using the same. The method of manufacturing the superparamagnetic nanocomposite according to the present invention has a higher yield and a high rate without complicated processing than a conventional method of manufacturing a magnetic nanoparticle for magnetic separation and is capable of mass production of the superparamagnetic nanocomposite having excellent properties with uniform size and particle size distribution, high aqueous solution dispersibility and high magnetization and being capable of maintaining superparamagnetism.
First claim
Opening claim text (preview).
The invention claimed is: 1. A superparamagnetic nanocomposite comprising a magnetic nanocrystal which is Fe 3 O 4 having a diameter of from more than 0 to 10 nm, wherein a surface of the magnetic nanocrystal is stabilized by carboxylate (COO—) group of dicarboxyl poly(ethylene glycol) having a molecular weight of 500 to 50,000, wherein the superparamagnetic nanocomposite has a plurality of magnetic nanocrystals clustered therein, has a nanoclustered shape having a diameter of 200 nm to 450 nm and has hydrophilicity so as to be dispersed in an aqueous solution.
