✦ Synopsis
After immersion of biomaterials into body fluids, tissues, or aqueous solutions, usually a surface charge can be experimentally detected. An electric double layer in the solidliquid interphase is built up by redistribution of charges (preferential adsorption of ions, dissociation of surface chemical groups, etc.). Surface potential estimations, though presumably not playing the key role in bio-and hernocompatibility tests, are widespread in biomaterial research and are being related to blood clotting time, protein-and blood cell adhesion.
It was observed by Coleman, Gregonis, and Andrade (1982)' that surface potentials
