| Outline of Final Research Achievements |
The ferrofluid, with Fe3O4 nano particles, coated with surfactant called oleic acid, and well dispersed in Sodium Dodecyl Sulphate (SDS) water solution, is a special type of nanofluid, and can be used as a contrast agent in MRI and hyperthermia. The diameter distribution of particles in a sample of this ferrofluid, TEM images and STEM images of magnetite nano partilces, and TEM images in solution in order to identify the type of ferrofluid.
To use ferrofluid as a contrast agent for MRI, T1 and T2 relaxation time at different temperatures and volume concentrations were measured by 12T NMR. Useful data have been measuring and storing, and some issues for ferrofluid as a MRI contrast agent are cleared in this study.
