Enhanced Neural Cell Adhesion and Neurite Outgrowth on Graphene-Based Biomimetic Substrates
Figure 2
Effects of graphene, SWCNTs, and MWCNTs on mitochondrial toxicity of PC-12 cells. Cells were treated with different concentrations of CNMs for 24 hours. At the end of the incubation period, the WST-8 assay was performed to evaluate the cytotoxicity as described in Section 2. Data were expressed as deviation (SD) based on at least duplicate observations from three independent experiments. The letter “a” indicates statistically significant difference from the untreated control; the letter “b” indicates statistically significant difference from cells treated with graphene at the same concentration ().
