According to the phenomena that inorganic salt may deposit on biological cell membrane and the biomineralization theory, under the man-made culture conditions, one kind of SiO2 nanostructured material with special shape was biominerally synthesized successfully by means of the cell templates of lower eukaryote-yeast and by tetraethyl orthosilicate(TEOS) as Si nutrition. In the yeast cell wall, the shell-like nanostructured SiO2 was synthesized, and its thickness was 150 nm. The samples were investigated by TEM, SEM, EDX, FT-IR, XPS, TGA, etc., and massive experimental data were obtained.
