Figure 5.
Visualization of cell viability on MWCNT-COOH-coated zirconia after 6 days by fluorescence microscope. High viability of the Saos-2 cells on MWCNT-COOH-coated zirconia is indicated. The green colored cells (calcein AM) indicate viable cells, and the red colored cells (ethidium homodimer-1) indicate dead cells.
