Antibacterial Activity of BSA-Capped Gold Nanoclusters against Methicillin-Resistant Staphylococcus aureus (MRSA) and Vancomycin-Intermediate Staphylococcus aureus (VISA)

摘要

The emergence of drug-resistant pathogens and the abuse of antibiotics have posed dominant threats to society. In this study, we propose an antibacterial use of bovine serum albumin-capped gold nanoclusters (BSA-AuNCs) to address the issue. BSA-AuNCs have a great antibacterial activity against MRSA and VISA which is proved by time-killing curves (TKC). The possible antibacterial mechanisms of BSA-AuNCs against MRSA and VISA are confirmed by fluorescence image observation.
