| 1 | Synthesis of Zinc Oxide Nanoparticles with Good Photocatalytic Activities under Stabilization of Bovine Serum Albumin显示文摘Zinc oxide nanoparticles were synthesized using bovine serum albumin as stabilizers through a facile one-pot strategy in aqueous media. The morphology and crystal phase of the zinc oxide nanoparticles were determined by transmission electron microscopy, X-ray diffractograms, and Fourier transform infrared spectroscopy. The synthesized ZnO nanoparticles exhibited strong absorption and photoluminescence properties in the visible wavelength region based on the fluorescence and UV-visible spectroscopy. Based on the results, the zinc oxide nanoparticles could effectively degrade the organic dyes through the mediation of the hydroxyl radical under visible light irradiation. Furthermore, the zinc oxide nanoparticles show good recycling stability during the photocatalytic experiments. These results suggested that the as-prepared zinc oxide nanoparticles might be used as a potential photocatalyst to efficiently treat the organic pollutants. | 陈稚 SHUAI Li ZHENG Bodan WU Dudu | 2017 | Journal of Wuhan University of Technology(Materials Science)2017，32，5： | 2 |
| 2 | Assessment of Toxicity of BSA-conjugated Zinc Oxide Quantum Dots for C2C12 Cells显示文摘Colloidal semiconductor nanoparticles (quantum dots, QDs) have attracted a lot of interests in numerous biological and medical applications due to their potent fluorescent properties. However, the possible toxic effects of quantum dots remain an issue of debate. In this study, we aimed to evaluate the cytocompatibility of bovine serum albumin (BSA) conjugated zinc oxide QDs for C2C12 cells. In the experiment, ZnO QDs were synthesized by using BSA as the structure directing agent, and the morphology and crystal phase of ZnO QDs were determined by transmission electron microscopy, X-ray diffractograms and Fourier transform infrared spectrograph techniques. The inverted fluorescence microscope results showed that ZnO QDs were distributed inside the cells. The toxicity of ZnO QDs was assessed by MTT methods, which revealed that ZnO QDs were highly cytocompatible in the concentration less than 200 μM. However, when the concentration of QDs was higher than 1 000 μM ZnO QDs showed significantly toxicity, which was ascribed to generation of free zinc and formation of reactive oxygen species (ROS). Furthermore, the morphological observations exhibited that cells treated with ZnO QDs showed altered morphology, depolymerized cytoskeleton and irregular-shaped nuclei. This study provides helpful guidances on the future safe use and manipulation of QDs to make them suitable tools in nanomedicine. | 陈稚 LI Baohong ZHENG Bodan XING Xiaowei 吴都督 | 2019 | Journal of Wuhan University of Technology(Materials Science)2019，34，3： | 0 |
