This study was performed to evaluate the effects of a diamond-like carbon (DLC) layer on the biological properties of a pretreatedtitanium dioxide (TiO2) coronary stent surface. TiO2and DLC were coated onto a cobalt-chromium stent surface inconsecutive order using the plasma-enhanced chemical vapor deposition method (TiO2/DLC). To investigate the effect ofTiO2,a group treated only with DLC was also prepared as a control. The surface characteristics were investigated by SEM,ESCA, AFM, and contact angle analyses. To estimate the effect of surface modification on biological response, endothelialcell migration was carried out. As a result, cracking of the coating layer on the strut curved portion in the DLC group wasrestored in the TiO2/DLC group. ESCA result showed that the peaks sp2 and sp3 were slightly shifted and higher in the TiO2/DLC group. The surface roughness average was highly increased in the TiO2/DLC group (Ra; 18.033) compared to the BMS(Ra; 9.258) and DLC groups (Ra; 10.144). By the increment of Ra, the surface property became hydrophilic in the TiO2/DLC group (39.8° ± 5.88°) compared to the non-treated (72.7° ± 2.24°) and DLC (78.6° ± 2.24°) groups. Endothelial cellmigration was significantly increased in the TiO2/DLC group (68.9 ± 13.52%) compared to the non-treated (5.4 ± 3.14%) andDLC groups (22.3 ± 8.22%). Therefore, the improvement of surface properties and endothelial cell migration in the TiO2/DLC group could improve the physiological response in the human body.
