Liquid-Phase Exfoliation and Functionalization of MoS2 Nanosheets for Effective Antibacterial Application

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 (Amp(R) 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.
