摘要
Multifunctional core-shell nanostructures formed by integration of distinct components have received wide attention as promising biological platforms in recent years. In this work, crystalline zeolitic imidazolate framework-8 (ZIF-8), a typical metal-organic framework (MOF), is coated onto single gold nanorod (AuNR) core for successful realization of synergistic photothermal and chemotherapy triggered by near-infrared (NIR) light. Impressivel)~ high doxorubicin hydrochloride (DOX) loading capacity followed by pH and NIR light dual stimuli-responsive DOX release can be easily implemented through formation and breakage of coordination bonds in the system. Moreover, under NIR laser irradiation at 808 nm, these novel AuNR@MOF core-shell nanostructures exhibit effective synergistic chemo-photothermal therapy both in vitro and in vivo, confirmed by cell treatment and tumor ablation via intravenous injection.
