Abstract Gold nanoparticles were synthetized in short time by a novel and easy method by using an aqueous extract from Agave potatorum. The UV–Vis data show a characteristic band at 540 nm, from the minute 2 of synthesis that intensifies through the reaction time advances, by X-Ray diffraction and Selected Area Electron Diffraction (SAED), it is demonstrated the polycrystallinity of the samples, exhibiting the specific features of metallic gold; the Transmission Electron Microscopy (TEM) results show pseudospherical nanoparticles with an average size of 14 nm corresponding to the synthesized samples at 10 min and 22 nm in the case of the synthesized samples at 20 min. The results suggest that the Agave extract works also as stabilizer.

使用龙舌兰马铃薯提取物在低温下快速合成金纳米粒子

摘要 以马铃薯的水提液为原料，采用一种新颖、简便的方法在短时间内合成了金纳米粒子。UV-Vis 数据显示 540 nm 处的特征带，从合成的第 2 分钟开始，随着反应时间的推进，通过 X 射线衍射和选区电子衍射 (SAED)，证明了样品的多晶性，表现出金属金的特性；透射电子显微镜 (TEM) 结果显示伪球形纳米粒子的平均尺寸为 14 nm，对应于 10 分钟的合成样品和 22 nm 的合成样品，在 20 分钟的情况下。结果表明龙舌兰提取物也可作为稳定剂。
