Albumin adhesion on ceramics and correlation with their Z-potential.

An investigation into albumin adhesion on ceramics was carried out, providing useful information on the relationship between the Z-potential of ceramic materials and the amount of closely adhered albumin. The chemical nature of the substance constituting the ceramic is mainly responsible for the adhesion, but additional influencing factors are also considered. A differentiation in the amount of adhesion (which is a consequence of the forces of attraction between the ceramic surface and the molecules of albumin) is found and concerns the biological quality of the materials, particularly the bioactive and bioinert ceramics.
