The increasing demand and limited natural resources of noble metals make its recovery from dilute industrial wastes attractive, especially when using environmentally friendly methods. Nowadays, the high impact that nanotechnology is having in both science and society offers new research possibilities. Gold and silver nanoparticles were biosynthesised by a simple method using different algae as reducing agent. The authors explored the application of dead algae in an eco-friendly procedure. The nanoparticle formation was followed by UV-vis absorption spectroscopy and transmission electron microscopy. The functional groups involved in the bioreduction were studied by Fourier transform infrared spectroscopy.
日益增长的需求和有限的贵金属资源使其从稀有的工业废料中回收变得具有吸引力,特别是当使用环保方法时。如今,纳米技术在科学和社会中产生的巨大影响提供了新的研究可能性。金和银纳米粒子通过使用不同藻类作为还原剂的简单方法生物合成。作者探索了死藻在环保程序中的应用。通过紫外可见吸收光谱和透射电子显微镜跟踪纳米粒子的形成。通过傅里叶变换红外光谱研究了参与生物还原的官能团。
