Cancer‐Mitochondria Dual‐Targeting Glycol/Ferrocenium‐Based Polydopamine Nanoparticles for Synergistic Photothermal and Photodynamic Therapy

A cancer-mitochondria dual-targeting nanoparticle based on lactose and ferrocenium derivatives conjugated polydopamine (PDA@Lac/Fc/Hyp) was constructed, which exhibited cancer-targeting and mitochondria-targeting ability deriving from lactose and ferrocenium derivatives due to the specific carbohydrate-protein interaction and cationic species properties, respectively. Moreover, PDA@Lac/Fc/Hyp showed great biocompatibility and phototherapeutic efficiency. This work displays a good example of constructing cancer-mitochondria dual-targeting nanoparticle for synergistic phototherapy.
