Notes:
Ultrasmall superparamagnetic iron oxide nanoparticles (USPION) as magnetic resonanceimaging were synthesized through a sonochemical co-precipitation method with poly(ethyleneimine) (PEI). The size of the USPION was controlled by poly (ethyleneimine) (PEI)contents, ultrasonic exposure time, and Na4OH concentration. The characteristics of PEI-USPIONwere studied by X-ray diffractometry, magnetic property measurement system, scanning electronmicroscopy, transmission electron microscopy, and particle size analysis. The PEI-USPION had anaverage size of 5~10nm with a narrow size distribution, a perfect magnetite crystal structure, andhigh saturation magnetization
