One of the important points in the use of magnetic nanoparticles for biomedical applications is the encapsulation of the magnetic material, in order to make it biocompatible, producing a bio-ferrofluid. In this paper, ferrimagnetic particles of
Fe3O4 were nanometrically synthesized. In order to coat a photosensitizer on the magnetic particles, TSPP was choosed and introduced into the ferrofluid suspension containing magnetite and the adsorption reaction was conducted at 60, 70,and 80o C. Analytical investigations (UV-Vis, TEM, XRD, TGA) argued the TSPP encapsulated into Fe3O4.
