[Study on the adsorption of collagen onto surfaces with imaging ellipsometry].
The adsorption of collagen onto hydrophilic and hydrophobic surfaces was studied with imaging ellipsometry in different pH, adsorption time, ion strength and BSA existence. The results showed that there was more collagen adsorbed onto hydrophobic surfaces than onto hydrophilic surfaces. The maximum collagen adsorption was observed at pH 7.2. The existence of BSA affected the adsorption of collagen onto hydrophobic surfaces more than that onto hydrophilic surfaces.
