Facile fabrication of uniform silica films with tunable physical properties using silicatein protein from sponges.


We report an elegant and simple method to fabricate uniform silica films with controlled thickness, roughness, and hydrophilicity using nanogram quantities of silicatein, a protein involved in silica synthesis in sponges. The formation of uniform silica films was achieved by immobilization of silicatein on gold-coated surfaces that had been functionalized… (More)
