SUPERPARAMAGNETIC IRON OXIDE NANOPARTICLES COATED WITH MANNAN, PREPARATION METHOD THEREOF AND CONTRAST AGENT FOR DIAGNOSING LIVER DISEASES

摘要

A mannan-coated superparamagnetic iron oxide nanoparticle is provided, which enables specific flow of liver to kupffer cell and ensure stability of ferrofluid. A contrast media for diagnosing hepatism comprises a mannan coated superparamagnetic iron oxide nanoparticle. A method for manufacturing the nanoparticle comprises: a step of adding basic solution in iron chloride aqueous solution and dipping iron oxide nanoparticle; a step of oxidizing the iron oxide nanoparticle and producing storage solution; and a step of mixing mannan solution in the storage solution, stirring and coating.
