Scanning electron micrographs of the products of the reaction between silicon alkoxides and silicatein or cellulose filaments. (A) Silicatein filaments before the reaction. (B) Silicatein filaments after a 12-h reaction with TEOS (1.0 ml; 4.5 mmol) plus Tris⋅HCl buffer. (C) Air-dried silicatein filaments incubated with TEOS as in B, but with no additional water. (D) Silicatein filaments after an 8-h reaction with phenyltriethoxysilane (1.0 ml; 4.1 mmol) plus Tris⋅HCl buffer. (E) Cellulose fiber. (F) Cellulose fiber after a 12-h reaction with TEOS as in B.
