Biomimetic syntheses of silicas using block copolypeptides containing a hydrophilic lysine block are reported. Porous silica platelets or spheres can be made using block copolypeptides as templates. The results show that biomimetic synthesis under benign conditions may be a potential route for assembling nanostructured materials.
