Use of commercial products containing nanoparticles formulated from zinc oxide (ZnO) and aluminium oxide (Al2O-3) has increased significantly. These nanoparticles are widely used as ingredient in cosmetics, and also in food packaging industry although their toxicity status is yet to be studied. Here, we aimed to explore the effect of zinc oxide nanoparticles (ZnO-NPs) and aluminium oxide nanoparticles (ANPs) in human HT29 colon cancer cell line.
In this study, ZnO-NPs were synthesized by chemical method and ANPs synthesized by sol-gel method and were characterized using UV-Vis spectroscopy, X ray diffraction and Transmittance electron microscopy. The effects of ZnO-NPs and ANPs was determined by cell viability, membrane integrity and colony formation potentials.
ZnO-NPs and ANPs inhibit HT29, colon cancer cell proliferation in a dose dependent manner, and affect the membrane potentials and also prevent the colony formation.
The results suggest that ZnO NPs are found to be more effective than ANPs in reducing colon cancer cell proliferation.

在本研究中,ZnO-NPs通过化学方法合成,ANPs通过溶胶-凝胶法合成,并使用紫外-可见光谱、X射线衍射和透射电子显微镜进行表征。通过细胞活力、膜完整性和集落形成潜力来确定ZnO-NPs和ANPs的作用。
ZnO-NPs和ANPs以剂量依赖性方式抑制HT29结肠癌细胞增殖,并影响膜电位,还能阻止集落形成。
结果表明,在减少结肠癌细胞增殖方面,ZnO NPs比ANPs更有效。
