Microorganisms play an important role in the eco-friendly synthesis of metal nanoparticles. This study illustrates the synthesis of gold nanocubes using the bacterium Bacillus licheniformis after 48 h of incubation at room temperature. The morphology of the samples was analyzed using scanning electron microscopy (SEM) and the particles formed were characterized to be nanocubes. The size of gold nanocubes in aqueous solution has been calculated using UV-Vis spectroscopy, XRD and SEM measurements. The nanoparticles are found to be polydisperse nanocubes in the size range 10-100 nm.
微生物在金属纳米颗粒的生态友好合成中发挥着重要作用。本研究阐述了在室温下培养48小时后,利用地衣芽孢杆菌合成金纳米立方体的过程。使用扫描电子显微镜(SEM)分析了样品的形态,所形成的颗粒经表征为纳米立方体。通过紫外可见光谱、X射线衍射(XRD)和SEM测量计算了水溶液中金纳米立方体的尺寸。发现这些纳米颗粒是尺寸范围在10 - 100纳米的多分散纳米立方体。
