Nanobiotechnological approach to engineered biomaterial design: the example of elastin-like polymers

Today, the development of advanced biomaterials is still lacking an appropriate tailored engineering approach. Most of the biomaterials currently used have their origin in materials developed for other technological applications. This lack of adequate biomaterial design is probably due to the peculiar environment where those materials must operate. On the one hand, this environment is dominated by the immune rejection system. On the other hand, the functionality of natural biomolecules is based on complex topological physical-chemical function distributions at the nanometer level. This review presents arguments concerning the role of biotechnology and nanotechnology in the future development of new advanced biomaterials and the potential of these biomaterials as a way to achieve highly biofunctional and truly biocompatible biomaterials for hot areas, such as regenerative medicine and controlled release. Recombinant protein-polymers will be presented as an example of candidates for this new paradigm in biomaterial design and production.
