Abstract

In this present study explores the multifunctional potential of ZnO@CA/PCL nanocomposites, delving into their efficacy in wastewater treatment and exhibiting promising in vitro anticancer activity. The prepared nanocomposites were characterized by Scanning SEM, TGA, XRD, UV–vis spectroscopy, X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared spectroscopy (FTIR). The results of an invitro anticancer activity showed the significant cytotoxic effect of ZnO nanoparticles on the ACHN renal cancer cell line. The photocatalytic activity of ZnO@CA/PCL nanocomposites were evaluated by monitoring the degradation of congo red (CR) and rhodamine-B (RhB) dyes under UV illumination. The degradation efficacy of the rhodamine-B (90%) was higher than that of the congo red dye (80%) after 60 min of irradiation under UV light.

评估 ZnO 注入 CA/PCL 纳米复合材料的废水处理潜力和体外抗癌活性

本研究探讨了 ZnO@CA/PCL 纳米复合材料的多功能潜力，深入研究了其在废水处理方面的功效，并显示出良好的体外抗癌活性。制备的纳米复合材料通过扫描电子显微镜、热重分析、X射线衍射、紫外-可见光谱、X射线光电子能谱（XPS）和傅立叶变换红外光谱（FTIR）进行了表征。体外抗癌活性研究结果表明，氧化锌纳米颗粒对 ACHN 肾癌细胞株具有显著的细胞毒性作用。通过监测紫外光照射下刚果红（CR）和罗丹明-B（RhB）染料的降解情况，评估了 ZnO@CA/PCL 纳米复合材料的光催化活性。在紫外光下照射 60 分钟后，罗丹明-B 的降解效率（90%）高于刚果红染料的降解效率（80%）。
