Abstract
ZnO quantum dots (QDs) have received much attention as biomarkers and drug delivery systems in cancer treatment, due to their low cost, ease of preparation, and pH-responsive degradation. However, its applications are limited by the low quantum yield and light absorption. In this work, a lanthanum-doped zinc oxide (La-ZnO) QDs-based drug delivery platform was constructed. The results show that 4% La doping is the most beneficial for improving the fluorescent properties of the ZnO QDs. After loading the drug, the cell activity was 15% at ZnO@DOX and 12% at La-ZnO@DOX. According to in vitro and in vivo experiment results, the La-ZnO QDs show enhancement of the antitumor effect. Dual enhancement of fluorescence and anti-tumor effects make La-ZnO QDs promising as a drug delivery system in cancer treatment.
