Silver Nanoparticles: the Invisible Soldiers in Antibacterial Armamentarium with a Spectroscopic Identity

EasyChair Preprint 11227

Abstract

Silver nanoparticles (AgNPs) have emerged as a potent and versatile tool in the field of antibacterial research. Their exceptional antimicrobial properties make them an invaluable asset in the ongoing battle against drug-resistant pathogens. This review delves into the use of AgNPs as invisible soldiers in the antibacterial armamentarium, highlighting their effectiveness, mechanisms of action, and the role of spectroscopy in characterizing these nanoparticles.AgNPs exhibit remarkable antibacterial activity against a wide range of bacteria, including drug-resistant strains. This attribute is due to their unique physicochemical properties, such as size, shape, and surface charge. AgNPs can disrupt bacterial cell membranes, penetrate cells, and induce oxidative stress, ultimately leading to bacterial death. The ability to target multiple bacterial mechanisms has made AgNPs an attractive option for combating infectious diseases. Spectroscopy plays a crucial role in characterizing AgNPs. Techniques like UV-Vis spectroscopy, X-ray photoelectron spectroscopy (XPS), and Fourier-transform infrared (FTIR) spectroscopy allow researchers to monitor the size, shape, stability, and surface chemistry of AgNPs. This information is essential for tailoring AgNPs to specific antibacterial applications and ensuring their safety and efficacy.
