Publication number: 20120045399Abstract: Provided are a positively-charged superparamagnetic iron oxide nanoparticle (SPION), a contrast agent using the same, and a method of preparing the same. The positively-charged SPION includes a SPION, a polymer layer including a polymer containing many carboxyl groups coated on a surface of the SPION, and a cationic material coupled via an amide bond to a surface of the polymer layer. Therefore, the SPION may be prepared in a simple and reproducible process to have hydrophilicity and a strong positive charge. The prepared positively-charged SPION may have high uptake into a cell and stability, and be used in various applications as an effective contrast agent through non-invasive in vivo imaging.Type: ApplicationFiled: January 25, 2011Publication date: February 23, 2012Inventors: Yongdoo CHOI, Hyunjin Kim, Yun-Hee Kim, Daehong Kim, Inhoo Kim
