Existing studies examining the mechanism of mussel adsorption on inorganic surfaces show to be due to bidentate bonding of metal atoms on material surfaces by OH groups of catechol. We demonstrate that maleic acid (MA), which has similar functional groups, will provide adsorption on the surface of both hydroxyapatite (HA) and rutile titanium oxide (TiO2). Using first principles, models of MA monomer and MA with two hydrogen-terminated carbon atoms were added to mimic a polymer chain, were adsorbed separately to the surfaces of TiO2 and HA. The surface was treated in a vacuum, in a 60% ethanol/40% H2O solution, and a 100% H2O environment. In all cases, the surface energy in the relaxed state was favourable compared to the situation without the presence of MA. Due to the biocompatibility of MA, this shows use in biomedical applications to provide a better adhesive for implants.
