초록

Since chelating chemical had focused for enhancing bio-susceptibility and ability for the binding with biomaterials, in this study, Nitrilotiriacetic acid (NTA) was utilized for the developing chelate ligand attached superparamagnetic nanoparticle. In order to conjugate NTA, carboxylic group was needed on the surface of substrate particle for building peptide bond with amine group which was branched from the NTA structure. Therefore Fe3O4 nanoparticle was functionalized with various of amine precursor (Polyethyleneimine (PEI), (3-Aminopropyl)triethoxysilane (APTES)), and carboxyl precursor (Polyacrylic acid (PAA)) before the conjugation of NTA. Then NTA conjugation behavior was estimated which is varied with the type of amine precursor which affects to the surface properties.
