Glutathione‐Responsive Heterogeneous Metal–Organic Framework Hybrids for Photodynamic‐Gene Synergetic Cell Apoptosis

A core-shell heterogeneous metal-organic framework (MOF) hybrid is sequentially designed by a photosensitized porous coordination network (PCN)-typed MOF as core and Cu2+ -centered zeolitic imidazolate framework (ZIF-67) as shell encapsulating cyanine 3-labelled siRNA. The heterogeneous MOF hybrid realized stimulus-responsive photodynamic therapy (PDT) and controllable siRNA delivery through 1 O2 -assistant endosomal escape for imaging-guided photodynamic-gene synergetic theranostics.
