(1)背景：人们越来越需要开发用于合成纳米颗粒的新方法。对这种颗粒的兴趣已经引起了对其生产方法的环境安全性的关注;（2）目的：目前的纳米颗粒生产方法通常是昂贵的，并且使用对环境有潜在危害的化学品，这要求开发“更绿色”的方案。本文描述了利用植物提取物合成金纳米颗粒（AuNPs）的方法，该方法提供了一种替代的、高效的、廉价的和环境友好的方法来制备具有明确几何形状的纳米颗粒;（3）方法：存在于水溶性叶提取物中的植物化学物质作为有效的还原剂。通过透射电子显微镜（TEM）、扫描电子显微镜（SEM）、原子力显微镜（AFM）、X射线衍射（XRD）、紫外-可见光谱、能量色散X射线（EDX）和热重分析（TGA）对所制备的金纳米粒子进行表征;（4）结果与结论：所制备的纳米颗粒被认为是生物相容的，并没有表现出抗菌或抗真菌作用，认为该颗粒在纳米医学的各种应用中是安全的。TGA分析显示，存在于植物提取物中的生物分子覆盖了纳米颗粒并充当稳定剂。
(1) Background: There is a growing need for the development of new methods for the synthesis of nanoparticles. The interest in such particles has raised concerns about the environmental safety of their production methods; (2) Objectives: The current methods of nanoparticle production are often expensive and employ chemicals that are potentially harmful to the environment, which calls for the development of “greener” protocols. Herein we describe the synthesis of gold nanoparticles (AuNPs) using plant extracts, which offers an alternative, efficient, inexpensive, and environmentally friendly method to produce well-defined geometries of nanoparticles; (3) Methods: The phytochemicals present in the aqueous leaf extract acted as an effective reducing agent. The generated AuNPs were characterized by Transmission electron microscopy (TEM), Scanning electron microscope (SEM), and Atomic Force microscopy (AFM), X-ray diffraction (XRD), UV-visible spectroscopy, energy dispersive X-ray (EDX), and thermogravimetric analyses (TGA); (4) Results and Conclusions: The prepared nanoparticles were found to be biocompatible and exhibited no antimicrobial or antifungal effect, deeming the particles safe for various applications in nanomedicine. TGA analysis revealed that biomolecules, which were present in the plant extract, capped the nanoparticles and acted as stabilizing agents.
