Abstract

The development of the biological synthesis of nanoparticles using microorganisms or plant extracts plays an important role in the field of nanotechnology as it is environmentally friendly and does not involve any harmful chemicals. In this study, the synthesis of silver nanoparticles using the leaves extract of Chinese tea from Camellia sinensis is reported. The synthesized nanoparticles were characterized using UV-vis spectroscopy, X-ray diffraction (XRD), transmission electron microscopy (TEM), and Fourier transform infrared (FTIR) spectroscopy. The XRD analysis shows that the synthesized silver nanoparticles are of face-centered cubic structure. Well-dispersed silver nanoparticles with an approximate size of 4 nm were observed in the TEM image. The application of the green synthesized nanoparticles can be used in many fields such as cosmetics, foods, and medicine.

摘要

利用微生物或植物提取物进行纳米粒子的生物合成的发展在纳米技术领域中起着重要作用，因为它是环保的，并且不涉及任何有害化学物质。在这项研究中，报道了使用来自茶树的中国茶叶叶提取物合成银纳米粒子。使用紫外-可见分光光度法、X 射线衍射（XRD）、透射电子显微镜（TEM）和傅里叶变换红外（FTIR）光谱对合成的纳米粒子进行了表征。XRD 分析表明，合成的银纳米粒子具有面心立方结构。TEM 图像中观察到分散良好的银纳米粒子，其尺寸约为 4nm。绿色合成的纳米粒子的应用可以用于许多领域，如化妆品、食品和医药。
