Figure 7

Cell viability determined by MTT assay after 3, 5, and 7 days of cell culture on ZnAl2O4 (■) bulk material and (□) thin films nanostructured at °C. Error bars represent mean ± SE, cultures under each conditions. Asterisk denotes significant differences ( ) between ceramic materials as determined by Student’s -test.
