MoS2 Nanoclusters-Based Biomaterials for Disease-Impaired Wound Therapy

The document presents a study on the development of SA-MS hydrogel, a novel biomaterial combining MoS2 nanoclusters with sodium alginate hydrogel, aimed at treating wounds impaired by diseases such as diabetes and skin cancer. The hydrogel's porous microstructure allowed for the uniform distribution of Mo elements and the release of Mo4+ ions, which promoted cell migration, proliferation, and specific gene expression in human dermal fibroblasts, endothelial cells, and hair dermal papilla cells. In vivo experiments on diabetic mice and melanoma-bearing nude mice demonstrated that the hydrogel enhanced angiogenesis, hair follicle regeneration, and wound healing, while also exhibiting photothermal properties that suppressed skin cancer. The study concluded that SA-MS hydrogel is a promising material for disease-impaired wound healing and skin regeneration. The number of mice used in the in vivo experiments and the number of replicates in the in vitro assays were not specified in the summary provided.
