Resumo
In this study, we show and discuss the results of the interaction of living CHO (Chinese Hamster
Ovary) cells, in terms of adhesion and growth on glass, SU-8 (epoxi photoresist), PDMS
(polydimethylsiloxane), and DLC (hydrogen free diamond-like carbon) surfaces. Glass, SU-8, and
DLC but not PDMS showed to be good surfaces for cell growth. DLC surfaces were treated by
oxygen plasma (DLC-O) and sulfur hexafluoride plasma (DLC-F). After 24 h of cell culture, the
number of cells on DLC-O was higher than on DLC-F surface. SU-8 with silver implanted,
creating nanoparticles 12 nm below the surface, increased significantly the number of cells per unit
area.
