Abstract

We prepared an organotitanium molecular layer on stainless-steel (SUS316L) substrates, and evaluated its blood compatibility in terms of blood-clotting time and fibrinogen adsorption properties. Titanium methacrylate triisopropoxide (TMT) was used as the organotitanium molecule. The surface was characterized by contact angle measurement toward distilled water and Fourier transform infrared spectroscopy using a reflection absorption method (FT-IRRAS). The obtained organotitanium molecular layer had little effects on the blood-clotting times such as active partial thromboplastin time (PTT) and prothrombin time (PT). Bovine fibrinogen adsorption on the layer was examined from the absorbance of amide I peak in FT-IRRAS spectra. The organotitanium molecular layer reduced the amount of adsorbed fibrinogen compared with stainless-steel.
