From: Comparison of cytotoxicity of black phosphorus nanosheets in different types of fibroblasts
a Measurement of cell viability (%) of three different types of cells NIH3T3, nHDF and HT1080 determined by CCK-8 assay. The concentration range of nanosheets (BPNSs) is 0–125 μg/mL and the incubational time periods are 24 h and 48 h. b LDH release profile of the same. The control was the cell line without any additives (0 μg/mL). The data have been represented with standard deviation (n = 3; mean ± SD, ANOVA/Tukey’s-test; *P < 0.05, **P < 0.01, ***P < 0.001)
