Abstract

A study aimed at evaluating how protein adsorption may modify the properties of poly(lactic acid) and how bone cell behavior could be modified by the presence of the proteins, on the different surfaces was presented. The effect of oxygen gas plasma treatment on surface-protein-cell interactions was also analyzed. A solution depletion technique and BCA assay were used to determine the amount of non-adsorbed proteins. The effect on the cells was observed by combining gas plasma modification of the surface with the protein adsorption.
