Molecular Modelling of Peptide-Based Materials for Biomedical Applications

Adv Exp Med Biol. 2017:1030:37-50. doi: 10.1007/978-3-319-66095-0_3.

Abstract

The molecular-level interactions between peptides and medically-relevant biomaterials, including nanoparticles, have the potential to advance technologies aimed at improving performance for medical applications including tissue implants and regenerative medicine. Peptides can possess materials-selective non-covalent adsorption properties, which in this instance can be exploited to enhance the biocompatibility and possible multi-functionality of medical implant materials. However, at present, their successful implementation in medical applications is largely on a trial-and-error basis, in part because a deep comprehension of general structure/function relationships at these interfaces is currently lacking. Molecular simulation approaches can complement experimental characterisation techniques and provide a wealth of relevant details at the atomic scale. In this Chapter, progress and prospects for advancing peptide-mediated medical implant surface treatments via molecular simulation is summarised for two of the most widely-found medical implant interfaces, titania and hydroxyapatite.

Keywords: Hydroxyapatite; Implant materials; Molecular simulation; Peptides; Titania.
