酵母细胞为模板矿化合成SiO2纳米结构材料的研究
摘要:
根据无机盐可以在生物细胞膜上沉积形成纳米结构材料的现象和生物矿化理论, 在人工培养条件下, 成功地以低等真核生物细胞-酵母菌为模板, 以正硅酸乙酯(TEOS)作为硅源, 矿化合成了一种壳鞘状的SiO2纳米结构材料, 厚度达150 nm左右, 并采用TEM、SEM、EDX、FT-IR、TGA等表征手段对实验结果进行了深入细致的研究, 获得了大量的实验数据, 为利用生物细胞模板合成介观尺寸有序SiO2纳米材料作出了有益的尝试.

Studies on Biomineral Synthesis of SiO2 Nanostructured Materials by Yeast Cells as Templates
Abstract:
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.
