The purpose of the study was to investigate the influence of the isoelectric point and residue of an amino acid on the adsorption of the amino acid by titanium in order to elucidate the adsorption of proteins by titanium. The direction of amino acid adsorbed by a titanium surface in an electrolytic solution was determined using X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared reflection absorption spectroscopy (FT-IR-RAS). Apparently, the influence of amino acid on the composition and thickness of surface films on titanium is minimal if the film is formed in an electrolytic solution. The pH of the electrolytic solution and the residue of amino acids are responsible for the direction of the amino acid adsorbed by surface film formed on titanium in solution.
本研究的目的是研究氨基酸的等电点和残基对钛吸附氨基酸的影响，以阐明钛对蛋白质的吸附作用。采用X射线光电子能谱（XPS）和傅里叶变换红外反射吸收光谱（FT-IR-RAS）测定了电解液中钛表面吸附氨基酸的方向。显然，如果在电解液中形成膜，氨基酸对钛表面膜的组成和厚度的影响很小。电解液的pH值和氨基酸残基决定了溶液中钛表面形成的表面膜吸附氨基酸的方向。
