Photo-excited antibacterial poly(Ɛ-caprolactone)@MoS2/ZnS hybrid nanofibers

The rapid and timely sterilization is quite important function for textiles to prevent human being from pathogenic bacterial infections. Hence, it is necessary to develop wearable fabrics with rapid and effective antibacterial properties. In this work, using one-step hydrothermal method and electrospinning, we synthesized biocompatible antibacterial hybrid nanofibers composed of poly(Ɛ-caprolactone) (PCL) incorporated with heterojunction of MoS2/ZnS (MZ). The MZ endowed the PCL-MZ nanofibers with excellent photothermal and photocatalytic properties under visible light. After 10 min visible light irradiation, the hybrid nanofibers with optimum proportion achieved an effective antibacterial efficacy of 96.03% and 99.09% against Staphylococcus aureus and Escherichia coli, respectively. The underlying mechanism is based on the synergistic effects of reactive oxygen species (ROS) and hyperthermia. Thus, the PCL-MZ hybrid nanofibers will be promising for the fabrication of wearable antibacterial fabrics.
