Novel nanostructured hematite–spongin composite developed using an extreme biomimetic approach

Abstract

The characteristic mineral-free fibrous skeletons (made of structural protein-spongin) of <italic>H. communis</italic> (Demospongiae: Porifera) was used as a structural template in hydrothermal synthesis of hematite (α-Fe₂O₃) nanoparticles.
