Abstract
ABSTRACTTo study the contribution of different surface feature properties in improving vascular endothelial cell adhesion, rationally designed nano/sub-micron patterns with various dimensions were created on titanium surfaces in this study. In vitro results indicated that endothelial cell adhesion was improved when the titanium pattern dimensions decreased into the nano-scale. Specifically, endothelial cells preferred to adhere on sub-micron and nano rough titanium substrates compared to flat titanium. Moreover, titanium with nano and sub-micron roughness and with the same chemistry as compared to flat titanium, had significantly greater surface energy. Thus, the present study indicated the strong potential of surface nanotopography and nano/sub-micron roughness for improving current vascular stent design.
