Gold Nanoparticle: Recent Progress on Its Antibacterial Applications and Mechanisms

Abstract

Gold nanoparticles (AuNP) is a new type of metal nanomaterials used in the biomedical field. Compared with ordinary metal materials and other metal nanomaterials, AuNP can be very unique. AuNP has been proven to have good performance against a variety of pathogens, and research on its antibacterial activity and mechanism has also become a hot topic in recent years. This article summarizes the antibacterial properties and clinical applications of AuNP against different kinds of bacteria and analyzes and discusses its existing and potential antibacterial mechanisms. At the same time, we also put forward the current challenges and problems to be solved by AuNP and look forward to its future development prospects, in order to correctly and comprehensively introduce this new antibacterial method.
