Název v původním jazyce

Cell adhesion and proliferation on poly(tetrafluoroethylene) with plasma-metal and plasma-metal-carbon interfaces

Popis výsledku v původním jazyce

The aim of this article is to investigate the e?ect of the interface between plasma activated, gold and carbon coated poly(tetra?uoroethylene) (PTFE) on in vitro adhesion and spreading of mouse ?broblasts (L929). Surface properties of pristine and modi?ed PTFE were studied by several experimental techniques. The thickness of a deposited gold ?lm is an increasing function of the sputtering time, conversely thickness of carbon layer decreases with increasing distance between carbon source and the substrate. Because all the used surface modi?cation techniques take place in inert Ar plasma, oxidized degradation products are formed on the PTFE surface, which a?ects wettability of the polymer surface. Cytocompatibility tests indicate that on samples with Au/C interface, the cells accumulate on the part of sample with evaporated carbon. Number of L929 cells proliferated on the studied samples is comparable to tissue culture polystyrene standard.
