Synthesis of silver nanoparticles and their applications on sensing technique

Abstract

Sterling silver is a very electrically and thermally conductive soft, white, glossy transition metal with a low melting point. In addition to coins and containers, it is used in lotions and ointments as well as foils for sutures and colloids as lotions and ointments. It is the most effective treatment for surgical and infectious illnesses. For all three of these reasons, silver nanoparticles are a fantastic material. The high surface-to-volume ratio of these materials has also contributed to their biological and antibacterial properties. Antimicrobial and sensor applications include silver nanoparticles, and medication delivery and optoelectronics include optomechanical devices. Ammonia sensing may make use of silver nanoparticles. When organic molecules decompose, ammonia is produced. It is also produced when gases are exchanged with the environment and nitrogen is fixed. It has many industrial applications. It is dangerous to breathe ammonia gas since it is poisonous to the eyes, nose, throat, and other mucous membranes. It was shown that Silver nanoparticles (NP) can be synthesized and characterized before they are used to treat germs that are harmful to humans. A chemical reduction technique utilizing starch as a capping agent was used to make ZnO NP, whereas a green synthesis procedure using AgNO3 solution and Citrus sinensis extract produced silver NP (sweet lime). UV-Vis spectroscopy, Dynamic Light Scattering (DLS) particle size analysis, Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD) analysis, and Thermogravimatric (TGA) analysis were used to characterize the nanoparticles in more detail. As determined by Dynamic Light Scattering (DLS) particle size and SEM image analysis, silver nanoparticles have an average particle size of 90 nm. The production of nanoparticles was verified via the use of XRD patterns, UV-VIS spectroscopy, and TGA.
