This study examined the effect of the treatment power on the enhanced cell attachment and proliferation on poly F-caprolactone (PCL) films treated with atmospheric plasma using a dielectric barrier discharge method (AP-DBD). The peak intensities of the -CH, C=O. -OH and -COO vibration modes, and binding energies of carbon and oxygen of the AP-DBD treated-PCL film increased with increasing plasma treatment power. The surfaces of the AP-DBD treated-PCL films were also examined for their in vitro cell adhesion properties using human prostate epithelial cells. The results showed that the level of cell attachment and proliferation on the AP-DBD treated-PCL film was ten times better than that observed on the untreated-PCL films. (C) 2008 Elsevier B.V.
