Furthermore, surface aspect such as surface roughness induced selective protein adsorption onto the biomaterial surface. The effect of surface quality on protein adsorption is also important to be understood because cells will attach to the protein adsorbed, instead of the material directly. This review paper critically analyses the role of surface quality on biocompatibility of biomaterials based on the information available in literature.
