Effect of fluorosurfactant on the adsorption of protein to synthetic hydroxyapatite

Abstract

I investigated the surface characterization of synthetic hydroxyapatite (HAp) treated with four types of fluorosurfactant (FSA) and its sequent effect on the adsorption of protein to HAp. The surface tension, zeta potential, chemical composition of the topmost surface and contact angle were measured for the HAp and dental enamel treated with FSA. The adsorption of protein on the surface of HAp treated with FSA was analyzed from the zeta potential as a function of protein concentration. The surface characterization of HAp changed with the coverage of FSA. Adsorption of FSA on the HAp surface prevented adsorption of protein.
