Suitability of Cell-Based Label-Free Detection for Cytotoxicity Screening of Carbon Nanotubes

Figure 8

Comparison of detection systems regarding decrease of viability to <80% (a) and significant increases compared to viability at 4 h (recovery (b)). Higher sensitivity of cells and systems is indicated in deeper shades of red color, while exposures with lack of cytotoxicity are indicated in green.
