dc.description.abstract | Objective therapeutics such as photodynamic therapy (PDT) play an imperative role where targeted delivery of nanotherapeutics could achieve the highest level of therapeutic efficiency for the treatment of cancer. For an effective combination of chemotherapy and PDT, a multimodal-targeted system is vital to achieving effective therapeutic efficacy to counter cancer. In this study, an upconversion nanoparticle-based dual-mode nanocarrier was established where doxorubicin, a chemotherapeutic drug, and tetra carboxy zinc phthalocyanine, a reactive oxygen species (ROS) generator, were successfully embedded onto metal-organic framework (ZIF-8) for synergistic photodynamic therapy. For controlled drug release, amine-PEG was wrapped around UCNPs@MOF. In addition, targeting efficiency was enhanced by employing a prostate cancer-specific ligand (folic acid, FA), which is recognized by prostate-specific membrane antigen (PSMA). Indeed, the nanocomposite-coupled FA was uptaken more in LNCaP (PSMA positive) cells compared to DU145 (PSMA negative) cells. Interestingly, coating the nanocomposite with biocompatible polyethylene glycol significantly inhibited doxorubicin (DOX) release even under a lower pH condition. This effect is abrogated by near-infrared irradiation, whereupon NIR irradiation, the nanocomposite accelerates the production of ROS, as well as chemotherapeutic drug release. These results suggest that the release of DOX was more tightly controlled by a polymer coating. As observed by in vitro cytotoxicity experiment, LNCaP cells showed descending pattern in the cell viability than DU145 cells under the NIR irradiation condition. All these results, taken together, show a promising system for NIR-based targeted PDT where burst release of drug and ROS is achieved to improve the synergistic therapeutics. © 2021 Elsevier Ltd | - |
