Abstract:

Silver nanoclusters are a class of silver nanomaterials whose particle sizes are between silver atoms and silver nanoparticles and consist of several to hundreds of silver atoms at a core size of less than 2 nm. In recent years,silver nanoclusters have attracted much attention in the field of antimicrobial application due to their inherent advantages such as broad-spectrum antibacterial activity,non-drug resistance,good biocompatibility and low dose effectiveness. In this paper,the antibacterial mechanisms and influencing factors of antibacterial activity of silver nanoclusters are reviewed,their cytotoxicity is discussed,and the existing antibacterial applications are summarized. The future application directions and breakthroughs of silver nanoclusters are prospected,and the wide application prospects of DNA silver nanoclusters are highlighted.

Key words: silver nanoclusters, antibacterial mechanism, antibacterial activity, cytotoxicity, DNA
