摘要:
A superparamagnetic nanoparticle is comprised of superparamagnetic nanocrystals less than 20 nm in size, and molecules having containing 3 to 5 carboxyl groups, wherein the molecules bond to surfaces of the superparamagnetic nanocrystals. A method for producing superparamagnetic nanoparticles includes preparing an alkaline solution with pH 10 to 14, producing a mixture in which molecules containing 3 to 5 carboxyl groups, a divalent transition metal and ferric precursors are dissolved, and adding the mixture into the alkaline solution.
