The application of "green" chemistry rules to nanoscience and nanotechnology is very important in the preparation of various nanomaterials. In this work, we successfully developed an eco-friendly chemistry method for preparing silver nanoparticles (Ag-NPs) in natural polymeric media. The colloidal Ag-NPs were synthesized in an aqueous solution using silver nitrate, gelatin, and glucose as a silver precursor, stabilizer, and reducing agent, respectively. The properties of synthesized colloidal Ag-NPs were studied at different reaction times. The ultraviolet-visible (UV-vis) spectra were in excellent agreement with the obtained nanostructure studies performed by transmission electron microscopy (TEM) and their size distributions. The prepared samples were also characterized by X-ray diffraction (XRD) and atomic force microscopy (AFM). The use of eco-friendly reagents, such as gelatin and glucose, provides green and economic attributes to this work.
在各种纳米材料的制备中，将“绿色”化学规则应用于纳米科学和纳米技术非常重要。在这项工作中，我们成功地开发了一种在天然聚合物介质中制备银纳米粒子（Ag-NPs）的环保化学方法。胶体 Ag-NPs 是在含有硝酸银、明胶和葡萄糖的水溶液中分别作为银前驱体、稳定剂和还原剂合成的。在不同的反应时间下研究了合成胶体 Ag-NPs 的性质。紫外-可见（UV-vis）光谱与通过透射电子显微镜（TEM）进行的获得的纳米结构研究非常吻合，并且它们的尺寸分布也一致。使用 X 射线衍射（XRD）和原子力显微镜（AFM）对制备的样品进行了表征。使用环保试剂，如明胶和葡萄糖，为这项工作提供了绿色和经济的属性。
