Biomineral‐forming organisms provide inspiration for developing new reaction pathways to functional materials, such as rutile for optical devices. A recombinant protein (rSilC) was designed based on the sequence of a silica‐forming protein from a diatom. This unique protein induced the formation of hierarchically nanostructured rutile microcrystals under mild reaction conditions (see SEM image).
