Paper Abstract

Numerous nanomaterials have been developed for biomedical application, especially cancer therapy. Visualizing cancer therapy is highly promising now because of the potential ability to realize accurate, localized treatment. In this work, we firstly synthesized metal nanorattles (MNRs), which utilized porous gold shells capable of photothermal therapy to carry multiple superparmagnetic iron oxide nanoparticles (SPIONs) as MR imaging contrast agents inside. As shown in the infrared light, these metal rattle-typed nanostructures were able to convert to heat to kill cells, and inhibit tumor growth. As a carrier for multiple SPIONs, it also performed a good behavior for T2-weighted MR imaging in tumor site. Moreover, the rest of the inner space of the gold shell also introduced potential ability as nanocarriers for other cargos such as chemotherapeutic drugs, which is still under investigation. This metal-rattle-type nanocarriers is highly potential as a novel platforms for cancer therapy in the future.
