Abstract：
The size of silver nanoparticles plays a crucial role in their ultimate application in the medical and industrial fields, as their efficacy is enhanced by decreasing dimensions. This study presents two chemical synthesis procedures for obtaining silver particles and compares the results to a commercially available Ag-based product. The first procedure involves laboratory-based chemical reduction using D-glucose (C6H12O6) and NaOH as reducing agents, while the second approach utilizes trisodium citrate dehydrate (C6H5Na3O7·2H2O, TSC). The Ag nanoparticle suspensions were examined using FT-IR and UV-VIS spectroscopy, which indicated the formation of Ag particles. The dimensional properties were investigated using Atomic Force Microscopy (AFM) and confirmed by Dynamic Light Scattering (DLS). The results showed particle size from microparticles to nanoparticles, with a particle size of approximately 60 nm observed for the laboratory-based TSC synthesis approach.
摘要：
银纳米粒子的尺寸对其在医疗和工业领域的最终应用起着至关重要的作用,因为它们的功效通过减少维度而增强。这项研究提出了两种用于获得银颗粒的化学合成程序，并将结果与市售的Ag基产品进行了比较。第一个程序涉及使用D-葡萄糖（C6H12O6）和NaOH作为还原剂的实验室化学还原，而第二种方法使用脱水柠檬酸三钠(C6H5Na3O7·2H2O，TSC）。使用FT-IR和UV-VIS光谱检查Ag纳米颗粒悬浮液，这表明Ag颗粒的形成。使用原子力显微镜（AFM）研究尺寸特性，并通过动态光散射（DLS）确认。结果显示从微粒到纳米粒子的粒径，对于基于实验室的TSC合成方法观察到的粒径约为60nm。
