Peptides and Peptide-based Biomaterials and their Biomedical Applications

Solid-binding peptides have been used increasingly as molecular building blocks in nanobiotechnology as they can direct the assembly and functionalisation of a diverse range of materials and have the ability to regulate the synthesis of nanoparticles and complex nanostructures. Nanostructured materials such as -sheet fibril-forming peptides and -helical coiled coil systems have displayed many useful properties including stimulus-responsiveness, modularity and multi-functionality, providing potential technological applications in tissue engineering, antimicrobials, drug delivery and nanoscale electronics. The current situation with respect to self-assembling peptides and bioactive matrices for regenerative medicine are reviewed, as well as peptide-target modeling and an examination of future prospects for peptides in these areas.

Fast-moving and rapidly expanding research area, which promises to be one of the most significant fields of research in applied biomedicine Highlights new developments in the applications of peptide and peptide-based biomaterials in biomedicine Introduces readers to direct applications and translational research at the interface between materials science, protein chemistry and biomedicine

Klappentext

This edited volume is composed of chapters written by experts in the field describing fundamental research on small peptide fragments in relation to their biological action and potential roles in biomedical applications from diagnosis to implant protection. It provides a review of the wide scope and significance of these relatively simple arrays of amino acids that have the ability to bind to surfaces of all kinds and can facilitate the autonomous assembly of structures in nanotechnology as well as penetrating cell membranes and delivering therapeutic drugs. Readers will learn of some of the impediments to a wider and more comprehensive catalog of these molecules and of some of the attributes of rationally-designed and chemically synthesised peptides as anticancer agents. An overview is provided of the expansive variety of biological leads for biomedically relevant peptides as well as the wide array of tissues and biological, bioactive scaffolds that are dependent on these short peptide sequences addressing topics such as cartilage and hard tissue initiation and regeneration and the transition of active reagents from molluscs to drug leads for the treatment of chronic pain. Peptides can possess surface-specific non-covalent adsorption properties that can be exploited to enhance the functionality of medical implant materials but their implementation is largely on a trial-and-error basis because an understanding of general structure/function relationships is lacking. Molecular simulation approaches can provide relevant details at the atomic scale and prospects for advancing peptide-mediated medical implant surface treatments via molecular simulation are summarized. The literature has papers emphasizing the role of peptides in the design of biohybrid functional surfaces and there has been a growing interest in applying peptides as materials-selective assemblers and self-organizers, but applications are based largely on an empirical understanding of solid surface binding characteristics, as reviewed here.

The present work is written for researchers who may be considering entering this field and are exposed to a mass of fundamental research information on individual applications. It has been our intention to trace how and where the research has emerged and to outline the opportunities we see to develop novel and well-grounded tools for specific therapeutic scenarios.
