In recent years, molybdenum disulfide (MoS2) as a typical class of two-dimensional (2D) materials has attracted wide attention because of its various fascinating properties. In this study, we fabricated MoS2 composite nanofibers by electrospinning technology combined with a doping method. The as-prepared MoS2 composite nanofibers exhibited excellent biocompatibility. In addition, the detailed investigation about the response of MoS2 composite nanofibers on bone marrow mesenchymal stem cells (BMSCs) indicated that the obtained MoS2 composite nanofibers could promote BMSC growth behavior, improve BMSC contact with each other, maintain cellular activity, and also provide positive promotion to regulate cellular proliferation. Moreover, the alkaline phosphatase expression significantly increased with increasing MoS2 concentration. Compared with the excellent biocompatibility and natural extracellular-matrix-like structure, we believe that the MoS2 composite nanofibers could provide new insight for the preparation of well-defined MoS2 nanostructure materials and will have promising potential in biomedical applications, such as tissue engineering, photothermal therapy, etc.
