The protein adsorption on the alginic acid layers covalently immobilized on stainless-steel and titanium was examined by Fourier transform infrared spectroscopy using a reflection adsorption method (FT-IRRAS). The relationship between platelet adhesion and protein adsorption was also investigated. The contact angle measurement and FT-IRRAS spectra confirmed the successful immobilization of γ-APS and alginic acid onto stainless-steel and titanium substrates. The result shows that less protein adsorption leads to blood-compatible surface on the alginic acid-immobilization.
