The present study reports an eco-friendly and rapid green synthesis method of silver nanoparticles (Ag-NPs). The silver nanoparticles were successfully synthesized using Chenopodium album as a reducing as well as capping agent simultaneously. The silver nanoparticles were characterized by UV-Visible absorption spectroscopy, Fourier transmission infrared (FT-IR) spectroscopy, X-ray diffraction (XRD) and scanning electron microscopy (SEM). The typical surface plasmon resonance of the Ag NPs was observed at ~ 428 nm. The X-ray diffraction analysis confirmed the silver nanoparticles had the face centered cubic (fcc) structure and the crystalline size was observed in the range of 10-30 nm. The SEM image illustrated that the particles were spherical in shape. In addition, the antibacterial activity of the silver nanoparticles was observed.

藜叶提取物的银纳米颗粒的绿色合成、表征和抗菌活性

本研究报告了一种环保且快速的银纳米颗粒（Ag-NPs）绿色合成方法。使用藜同时作为还原剂和封端剂成功合成了银纳米颗粒。通过紫外-可见吸收光谱、傅里叶透射红外 (FT-IR) 光谱、X 射线衍射 (XRD) 和扫描电子显微镜 (SEM) 对银纳米粒子进行表征。在 ~ 428 nm 处观察到 Ag NPs 的典型表面等离子体共振。X 射线衍射分析证实银纳米粒子具有面心立方 (fcc) 结构，观察到的晶体尺寸范围为 10-30 nm。SEM图像表明颗粒形状为球形。此外，观察到银纳米颗粒的抗菌活性。
