Fe (III) and Cu (II) doped polyaniline nano-compound and application thereof

Abstract

The invention provides a Fe (III) and Cu (II) doped polyaniline nano-compound and application thereof, belongs to the technical field of functional materials and particularly relates to a transition metal ion doped polyaniline nano-compound. The compound has good photo-thermal conversion, nuclear magnetic imaging and chemotherapy properties, can serve as a non-destructive tumor diagnosis and treatment reagent for nuclear magnetic imaging detection and thermo-chemotherapy on tumors. Copper (II) and iron (III) doped polyaniline nanoparticles are prepared through simple one-step reaction, the energy level of the conjugate structure of the polyaniline is changed after we support functional copper and iron metal ions in polyaniline having good biological compatibility, so that the extinction capability of the polyaniline in a near-infrared light area is remarkably improved, and the photo-thermal conversion performance is remarkably strengthened. In addition, the metal ion supported polyaniline nanoparticles have a good nuclear magnetic imaging function. The metal doped structure based on the coordination effect can also release the metal ions in a stimulated response environment, and the chemotherapy effect is produced by utilizing the toxicity of the metal ions.
