Introduction: The Road of Biomimetics The ideals of biomimicry are considered as some of the most prosperous ones among materials scientists of the modern day, who increasingly follow the biomimetic approach to design and fabrication of advanced materials [1-6].
Besides, as the number of atomic elements available to humans in the design of advanced materials and structures far exceeds that employed by the living organisms, it is natural to expect that not merely imitating and copying, but being inspired by, learning from and going beyond the natural design is the way forward for materials science and engineering of the future [153].
The question is why considering novel artificially produced materials as products of, literally, non-natural design.
The proteomic eye to follow the protein-related aspects of the process, and the materials science eye to follow the crystal formation facets.
