Atelocollagen-templated fabrication of tangled fibrous silica

Abstract

Protein-templated structured silica and titania are fabricated via a biomimetic method based on the synergistic effect of amine/carboxyl complexes under ambient conditions. Atelocollagen-templated silica showed a tangled fibrous structure with a smooth surface. The number of carboxyl groups of a protein is an important factor for homogeneous silica growth.
