Abstract

Abstract : The discovery and molecular (genetic) characterization of novel biological materials offers great potential to expand the range of soft materials used for biomedical applications. Abstract : An extensive range of biomaterials, frequently derived from extracellular matrix (ECM) proteins or other natural biopolymers, have been developed for biomedical applications. Their mechanical response, a key requirement for regenerative medicine, is often stiff but exhibits limited extensibility ( e.g. silk), or inversely, is compliant with higher strain to failure ( e.g. elastin). While synthetic biocompatible materials exhibiting a mechanical response between these boundaries are rare, several biological materials demonstrate unexpected combinations of these properties. In order to replicate these performance metrics in synthetic systems, a central requirement is to first reveal the molecular design of their constituent building blocks, which has traditionally been an extremely time-consuming task. Here, we highlight the recent application of Next Gen sequencing technologies for the characterization of several protein-based natural biopolymers, a technique which circumvents this research bottleneck. Successful molecular biomimicry of these model protein systems could thus have the potential to significantly expand the range of intrinsic material properties available for biomedical applications.
