Synthesis of Silver Nanoparticles and Their Applications: Review

Abstract

The synthesis of silver nanoparticles (AgNPs) has garnered significant attention due to their unique physicochemical properties and broad range of applications. This study explores various methods of synthesizing AgNPs, including chemical reduction, green synthesis using plant extracts, and physical methods such as laser ablation. The resulting nanoparticles were characterized using techniques like UV-Vis spectroscopy, X-ray diffraction (XRD), and transmission electron microscopy (TEM) to confirm their size, shape, and crystalline structure. AgNPs exhibit remarkable antibacterial, antifungal, and antiviral properties, making them valuable in medical applications such as wound dressings, coatings for medical devices, and drug delivery systems. Additionally, their catalytic activity and optical properties enable their use in environmental remediation, water treatment, and sensor development. This study highlights the synthesis processes, characterization, and potential applications of AgNPs, emphasizing their role in advancing nanotechnology and contributing to various fields, including medicine, environmental science, and material science.
