Core-shell metal-organic frameworks with fluorescence switch to trigger an enhanced photodynamic therapy.

ABSTRACT: The design of hybrid metal-organic framework (MOF) nanomaterials by integrating inorganic nanoparticle into MOF (NP@MOF) has demonstrated outstanding potential for obtaining enhanced, collective, and extended novel physiochemical properties. However, the reverse structure of MOF-integrated inorganic nanoparticle (MOF@NP) with multifunction has rarely been reported. Methods: We developed a facile in-situ growth method to integrate MOF nanoparticle into inorganic nanomaterial and designed a fluorescence switch to trigger enhanced photodynamic therapy. The influence of "switch" on the photodynamic activity was studied in vitro. The in vivo mice with tumor model was applied to evaluate the "switch"-triggered enhanced photodynamic therapy efficacy. Results: A core-satellites structure with fluo
