Abstract:

BACKGROUND: Superparamagnetic iron oxide has been widely used in biomedical applications, especially in the field of targeted diagnosis and therapy.

OBJECTIVE: To summarize the physicochemical property, preparation, surface modification, product testing and biomedical applications of superparamagnetic iron oxide.
METHODS: In order to search relevant articles about the physicochemical property and biomedical applications of superparamagnetic iron oxide from PubMed, Sciencedirect, CNKI and Wanfang databases (from 2000 to 2014), a computer-based search was performed using the keywords of “superparamagnetic iron oxide, preparation, coprecipitation, surface modification, magnetic resonance imaging contrast agent, fluorescent tracing, targeted therapy” in English and Chinese, respectively.

RESULTS AND CONCLUSION: The superparamagnetic iron oxide can be produced in the laboratory, and the preparation methods include hydrothermal method, vapor deposition method, mechanical milling method, liquid-phase microwave dielectric heating method, sol-gel method, emulsion method, co-precipitation method. Moreover, the superparamagnetic iron oxide can have different properties by surface modification and be applied in many biomedical fields, such as magnetic resonance contrast agent, fluorescent tracer, nanoparticle targeted therapy, hyperthermia and bioseparation.
