Abstract:
A lysozyme (Lys)-assisted liquid-phase exfoliation technique was designed to synthesize MoS2 nanosheets (MoS2 -Lys NSs). As a novel nanozyme antibacterial agent with high peroxidase-like catalyst activity, MoS2 -Lys NSs showed good antibacterial efficacy against both Gram-negative ampicillin-resistant Escherichia coli (Ampr E. coli) and Gram-positive Bacillus subtilis. A possible antibacterial mechanism is also proposed. This work provides an effective antibacterial strategy based on the MoS2 -Lys NSs antibacterial agent.
