Zinc(II)‐Dipicolylamine Coordination Nanotheranostics: Toward Synergistic Nanomedicine by Combined Photo/Gene Therapy

: We report the rational design of coordination-driven self-assembly metal-organic nanostructures for multifunctional nanotheranostics. Zinc(II) coordination-based nano-formulations capable of loading indocyanine green (ICG) and therapeutic genes were prepared to achieve a fluorescence/photoacoustic imaging-guided combination photo/gene therapy strategy. We showed the enhanced theranostic capability of zinc(II)-dipicolylamine-assisted assembly of ICG, as well as simultaneous targeted gene delivery in an experimental mouse model of cancer. Such a co-assembly strategy provides a facile way to achieve combined therapeutic functions for personalized nanomedicine.
