| 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TEOS(正硅酸乙酯)作为硅源矿化合成了一种壳鞘状的S iO2纳米结构材料,厚度达150nm左右,并采用TEM、SEM、EDX、TGA等手段对实验结果进行了表征,获得的实验数据为利用生物细胞模板合成介观尺寸有序S iO2纳米材料的提供了技术基础。

| 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 nanostructured material with special shape was biominerally synthesized successfully by means of the cell templates of lower eukaryote-yeast and the Si nutrition of TEOS.In the yeast cell wall,the shell-like nanostructured SiO_2 was synthesized,and its thickness is 150nm.The samples were investigated by TEM,SEM,EDX,TGA,etc.,and massive experimental data were obtained. |
