| Abstract: | In this paper,a kind of polypyrrole(PPY)@Fe3O4 nanoparticles with magnetic resonance imaging (MRI) and photothermal properties were prepared by utilizing the residual Fe ions as precursors to produce Fe3O4 crystals in situ on the surface of pre-synthesized PPY nanoparticles.The resulting PPY@Fe3O4 composite nanoparticles have prominent transverse relaxation time (T2)-weighted MRI effect and good photothermal properties,exhibiting good application prospects in the diagnosis and treatment of tumors. |
