An In Vitro Evaluation of the Biological Effects of Carbon Nanotube-Coated Dental Zirconia
Figure 8
SEM of Saos-2 cell on MWCNT-COOH-coated zirconia discs after treated with trypsin-EDTA (a) and its enlargement (b). One filopodium is still attached with a cluster of agglomeration of CNTs (a, b). Breakage of the filopodium could be due to the dehydration during the sample preparative process for SEM observation.
