Construction of coral rod-like MoS₂@HA nanowires hybrids for highly effective green antisepsis

Antibacterial materials have been rapidly emerging as a primary component in the mitigation of bacterial pathogens, and green functional materials play a vital role in the antibacterial field. In this study, biocompatible hydroxyapatite nanowires (HANW) was used as a carrier, a coral rod-like nanowires hybrid of MoS₂ and HANW (CR-MoS₂@HANW) was synthesized via a facile two-step hydrothermal approach. After being characterized by scanning electron microscope (SEM), energy dispersive spectrometer (EDS), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), fourier transform infrared spectroscopy (FT-IR), Brunauer-Emmet-Teller (BET) and thermogravimetric (TG) analysis, the antibacterial activity and environmental compatibility were assessed. It was found that MoS₂ nanosheets were in-situ assembled onto surface of HA nanowires, and the obtained nanohybrid exhibited excellent stability. CR-MoS₂@HANW endowed a desirable long-term antibacterial activity against both gram-negative E. coli and gram-positive S. aureus. It was sufficient to inhibit the growth of bacteria within 72 h, and nanohybrids effectively promoted the growth of plants. In summary, the combination of MoS₂ and HANW created a novel eco-friendly nanohybrids that could be applied as a promising multi-functional green antisepsis. And the CR-MoS₂@HANW possessed enormous potential for biomedical applications.
