| Research Abstract |
The purpose of this study was to investigate the real-time adsorption behavior of biological molecules and osteogenic cells on a light-induced superamphiphilic titanium surface using a quartz crystal microbalance(QCM). We showed the potential usefulness of QCM in elucidating the sequential interaction of biological molecules and cells with the tissue-material interface at the molecular level. The results suggest that photofunctionalization of Ti boosts the initial adsorption rate and increases the adsorptive capacity.
