摘要

The threat of bacteria and pathogens to human health and environmental safety has become a major public concern. In the fight against pathogenic bacteria, much effort has been expended on designing new antibacterial agents[1]. To date, various materials such as metals, oxides, N-halamines, polymers, chitosan, and graphene have been used as antibacterial agents[2,3]. Among them, silver-based materials in which Ag+ ions are generally the active species exhibit a highly bactericidal effect on a broad range of bacteria[4]. Recently, silver halides have been recognized as potent antimicrobial agents, with the release of Ag+ ions being a crucial aspect of their antibacterial function[5]. However, a challenge associated with the application of silver halides is their instability, and much work has been devoted to embedding them in a silica/polymer matrix to enhance their stability.
