Development of cost-efficient and eco-friendly biogenic synthetic protocols for the green synthesis of biocompatible metal nanoparticles has become popular among researchers in recent years. The biogenic synthesis of these nanoparticles and their potential biomedical applications introduces the concept of nanobiotechnology, which has become the latest fascinating area of research. The lower cost and lesser side effects as compare to chemical methods of synthesis are the main advantages of biosynthesis. In the present investigation, aqueous leaf extract of Plumbago zeylanica had been used to synthesize anisotropic gold nanoparticles. The as-synthesized gold nanoparticles were centrifuged at 5000 and 10000 rpm and compared both pellets using UV-visible spectroscopy, XRD, FTIR and TEM techniques. We have studied here the effect of speed of centrifugation on the yield, shape, size as well as size distribution of as synthesized gold nanoparticles.
近年来，开发用于绿色合成生物相容性金属纳米颗粒的经济高效且环保的生物合成方案在研究人员中颇受欢迎。这些纳米颗粒的生物合成及其潜在的生物医学应用引入了纳米生物技术的概念，这已成为最新的迷人研究领域。与化学合成方法相比，成本更低且副作用更小是生物合成的主要优点。在本研究中，白花丹的水叶提取物已被用于合成各向异性金纳米颗粒。将合成的金纳米颗粒以5000和10000转/分钟的转速离心，并使用紫外可见光谱、X射线衍射、傅里叶变换红外光谱和透射电子显微镜技术对两个沉淀物进行比较。我们在此研究了离心速度对合成的金纳米颗粒的产率、形状、尺寸以及尺寸分布的影响。
