Multifunctional Polypyrrole@Fe3O4 Nanoparticles for Dual-Modal Imaging and In Vivo Photothermal Cancer Therapy

Multifunctional Polypyrrole@Fe3O4 Nanoparticles for Dual-Modal Imaging and In Vivo Photothermal Cancer Therapy

Magnetic Fe3O4 crystals are produced in situ on preformed polypyrrole (PPY) nanoparticles by rationally converting the residual Fe species in the synthetic system. The obtained PPY@Fe3O4 composite nanoparticles exhibit good photostability and biocompatibility, and they can be used as multifunctional...

Zusammenfassung:Magnetic Fe3O4 crystals are produced in situ on preformed polypyrrole (PPY) nanoparticles by rationally converting the residual Fe species in the synthetic system. The obtained PPY@Fe3O4 composite nanoparticles exhibit good photostability and biocompatibility, and they can be used as multifunctional probes for MRI, thermal imaging, and photothermal ablation of cancer cells.
