An In Vitro Evaluation of the Biological Effects of Carbon Nanotube-Coated Dental Zirconia
Figure 4
Visualization of cell viability on uncoated zirconia after 6 days by fluorescence microscope. High viability of the Saos-2 cells on uncoated zirconia is indicated. The green colored cells (calcein AM) indicate viable cells, and the red colored cells (ethidium homodimer-1) indicate dead cells.
