Hollow ZrO 2 /PPy nanoplatform for improved drug delivery and real-time CT monitoring in synergistic photothermal-chemo cancer therapy

nanoplatform has been successfully demonstrated for synergistic photothermal-chemo therapy, both in vitro and in vivo. Due to the excellent X-ray attenuation ability of Zr, the biodistribution of this nanosystem was real-time monitored via CT imaging technology using mini swine as animal models. ICP-OES analysis of tissues obtained from the biopsy also confirms the biodistribution. The in vitro and in vivo toxicity evaluation shows that this nanosystem has good biocompatibility and has great prospects for imaging-guided photothermal-chemo cancer therapy.
