摘要

在这项初步研究中,我们展示了一种绿色合成纳米级金颗粒的环保工艺,该工艺使用澳大利亚本土植物巨桉(Eucalyptus macrocarpa)的叶子提取物作为稳定剂和还原剂。合成过程简单、清洁、无毒。它还具有在室温下进行,不需要复杂的加工设备的优点。通过紫外可见光谱、x射线衍射、透射电子显微镜和场发射扫描电子显微镜对纳米级金颗粒的形成进行了证实和表征。利用Kirby-Bauer灵敏度法对合成金颗粒的抗菌活性进行了定量测定。

Green biosynthesis of gold nanometre scale plates using the leaf extracts from an indigenous Australian plant Eucalyptus macrocarpa

Green biosynthesis of gold nanometre scale plates using the leaf extracts from an indigenous Australian plant Eucalyptus macrocarpa

In this preliminary study, we demonstrate an environmentally friendly process for the green synthesis of gold nanometre scale particles using the leaf extract from an indigenous Australian plant Eucalyptus macrocarpa as both the stabilising agent and the reducing agent. The synthesis process is straightforward, clean and non-toxic. It also has the advantages of being performed at room temperature and does not need complex processing equipment. Formation of the gold nanometre sized particles was confirmed and characterised by UV-visible spectroscopy, X-ray diffraction, transmission electron microscopy and field emission scanning electron microscopy. The antibacterial activity of the synthesised gold particles was also quantified using the sensitivity method of Kirby–Bauer.

期刊介绍: Gold Bulletin is the premier international peer reviewed journal on the latest science, technology and applications of gold. It includes papers on the latest research advances, state-of-the-art reviews, conference reports, book reviews and highlights of patents and scientific literature. Gold Bulletin does not publish manuscripts covering the snthesis of Gold nanoparticles in the presence of plant extracts or other nature-derived extracts. Gold Bulletin has been published over 40 years as a multidisciplinary journal read by chemists, physicists, engineers, metallurgists, materials scientists, biotechnologists, surface scientists, and nanotechnologists amongst others, both within industry and academia. Gold Bulletin is published in Association with the World Gold Council.
