Non-destructive investigation of fibronectin adsorption on titanium surfaces using PM-RAIRS: effect of surface hydroxylation

Abstract : Polarisation-modulation reflection-absorption infrared spectroscopy (PM-RAIRS) is a useful non-destructive technique to study semi-quantitatively the adsorption of proteins on metal surfaces. In this work, we employed PM-RAIRS to study the effect of the degree of hydroxylation of the surface of titanium metal sheets, obtained by specific acidic or basic treatments, on the adsorption of fibronectin, a model plasma adhesion protein. Our results seem to indicate that the degree of hydroxylation does not influence significantly the adhesion properties of fibronectin, which is one of the main steps in titanium osseointegration process.
