Greener Nanotech: A Comprehensive Review of Sustainable Synthesis Methods for Silver Nano-particles and their Applications

Over time, there has been a lot of interest in nanotechnology. Nanoparticles, which range in size from 1 to 100 nanometers, are made of metals, carbon, metal oxides, and organic materials. Because of their unique physical and chemical properties, silver nanoparticles (AgNPs) are becoming more and more common in a variety of industries, including consumer goods, food, healthcare, and medicine. When silver nanoparticles (AgNPs) interact with host or pathogenic cell proteins and enzymes, they cause the cells to die, exhibiting potent antimicrobial properties. Although there are several ways to make nanoparticles, chemical processes are the most widely used. Different techniques, classified as top-down or bottom-up approaches, are used to synthesize nanoparticles. Nanoparticles can be analysed using methods such as Fourier Transform Infrared (FT-IR) Spectroscopy, UV-Visible Spectroscopy, Transmission Electron Microscopy (TEM), and Scanning Electron Microscopy (SEM) to determine their potential and applications.
