Figure 3

Cytotoxicity of VGCF in each cell line. The cells were exposed to varying concentrations of VGCF for 24 hours. (A–E) Cell viability by Alamar blue assay (n = 8). The data are compared to DM. (F–J) Plasma membrane permeability by LDH assay (n = 3). PC; 0.01% Triton X-100.

Notes: LDH activity = (Experimental value – DM value)/(PC value – DM value) × 10 × 100%. Mean ± SE, *P < 0.05, **P < 0.01, ***P < 0.001.

Abbreviations: VGCF, vapor-grown carbon fiber; SB, Sumi black; LDH, lactate dehydrogenase; DM, dispersion medium.
