In vitro cell viability, migration and cytotoxicity of MN-MXenes-AS. A Confocal images of Living/Dead cell double staining of HUVEC after cocultured with different MN for 24 h and 72 h. B The cell viability of fibroblast cocultured with either MN-PGA, MN-AS, MN-MXenes, MN-MXenes-AS extract, or no materials for 72 h. C Cell viability of different groups after incubation with different concentration of AS for 72 h. D Photographic images of the migration of fibroblast incubated in normal cell culture medium (control) or cell culture medium containing AS or MN-MXenes-AS extract for 0 h, 6 h, 12 h and 24 h
