Abstract: This research investigated a novel folic acid(FA)-modified zirconium core metal-organic framework(MOF) Uio-66 as a nanocarrier to deliver indocyanine green(ICG) and Sunitinib to cancer cells for combination therapy. Platinum-loaded Uio-66 nanoparticles(Pu) were synthesized via a one-pot method, followed by the modification with FA on their surfaces. This afforded FPu that enabled subsequent loading of ICG and Sunitinib to achieve dual-modal cancer therapy. Drug loading/release test and singlet oxygen detection were also conducted in vitro, and the nanoparticles showed considerable drug loading efficiency for both ICG and Sunitinib, coupled with a high singlet oxygen generation rate. Specifically, drug loading and encapsulation efficiency of Sunitinib were 2.30% and 72.67%, while those for ICG were 2.87% and 90.28%, respectively. Additionally, cytotoxicity test on HepG2 human hepatocellular carcinoma cancer cell line revealed that the fully functional nanoparticles possess excellent biocompatibility and as such could be further investigated as a potential drug delivery system for effectual carcinoma cancer treatment.
