Abstract

Minerals are the benchmark of hard and brittle materials. Self-assembled calcitic spicules were recently obtained utilizing a protein from silica biomineralization, silicatein-α. The synthetic spicules show remarkable material properties including extreme flexibility. Breakthroughs in bio-inspired materials science are highlighted. Will it be possible to obtain similar composites with truly artificial organic constituents?
