AB  - PURPOSE: The purpose of this study was to investigate the adsorption of low 
      density lipoprotein (LDL) on titanium surface. METHODS: Pure titanium specimens 
      were soaked with different concentrations of LDL (0, 1, 2 mg/mL). Low density 
      lipoprotein essay was used to analyze the change of LDL adsorption on titanium 
      surface with time going on. Scanning electron microscope(SEM) and X-ray 
      photoelectron spectroscopy(XPS) were used to observe and analyze the adsorption 
      of LDL on titanium surface and its effect on element composition of titanium 
      surface. Contact angle of titanium surface was detected before and after LDL 
      adsorption. SPSS 22.0 software package was used for statistical analysis of the 
      data. RESULTS: The adsorption amount of LDL on titanium surface gradually 
      increased as time went on. XPS analysis results showed that LDL was adsorbed on 
      the titanium surface, the content of titanium and oxygen elements seemed to 
      decrease on the titanium surface, and the hydrophilicity of the titanium surface 
      declined. CONCLUSIONS: LDL can adsorb on titanium surface, which can change the 
      physical and chemical properties of titanium surface to a certain extent.
