The SEM-EDS showed that the content of surface elements was changed after treated with glutaraldehyde or albumin indicated that argon plasma only had surface cleaning effect and did not change surface composition and the allylamine deposition thickness was too thin to show the difference in SEM-EDS findings. The XPS results confirmed the argon plasma cleaning effect and revealed that the ratio and the binding energy of surface elements changed with different treatment procedures and were similar to what expected to coat on the titanium surface.
