显微镜

"The advantage of our method lies in the smallness, flexibility and precision with which the illuminated area of material can be chosen," Dwyer told nanotechweb.org."Hence, the experimentalist can precisely select the area of material she wants to analyse, and be confident that the surrounding areas are not interfering with her analysis."

对电子显微镜而言，由於物镜工作距离的限制，电子探针与样品常常无法同时被聚焦，因此大部分采用平行式探针的实验都是在探针离焦(out-of-focus)下进行，不幸的是，这种方法会产生如夫奈尔条纹之类多余的图形，因而不如易从绕射图形中精确选出待分析的样品体积。

Three RNAi target sites (named as Abil1, Abil2, Abil3) targeting the E3B1 (NCBI: NM-024397), an identified target sites and positive control GAPDH-A were selected. The pGenesil-1 eukaryotic expression vectors with the neoR mark and GFP green fluorescent mark were selected to construct E3B1 RNAi plasmid. The effect of RNAi targeting various sites on E3B1 genes expression was evaluated by testing the transfection efficiency with fluorescence microscope and western blot. The most effective siRNA in inhibiting E3B1 genes were screened. The most effective siRNA in inhibiting E3B1 genes screened and used to transfect the neuronal cells. After that, the inhibitor of axon growth was added and the axon growth was observed. Result: The siRNA expressing plasmids targeting the E3B1 were constructed successfully.

选择针对E3B1(NCBI： NM-024397)RNAi的3个靶位点Abil1、Abil2、Abil3和1个不针对任何mRNA的RNAi靶位点以及甘油醛－3-磷酸脱氢酶，用带有neoR选择标志和GFP绿色荧光标志的真核表达载体pGenesil-1构建E3B1 RNAi质粒，分别转染培养的神经元，在荧光显微镜下观测转染率，经G418筛选得到单一的转染细胞，并用Western blot法检测各转染组神经元E3B1蛋白的表达情况，选出具有最佳抑制效应的siRNA转染神经元，加入轴突生长抑制物，观测轴突生长情况。

Block-copolyimide film from pPDA/ODA-PMDA was studied by TEM, SEM, PLM, ultra-deep three-dimensional microscope, TMA, and WAXD, which showed that the extensile strength and modulus of b-PI film were higher than that of irregular copolyimide film. It was also revealed that there was a large amount of crystallite formed in b-PI film, which was mainly attributed to its chain structure: rigid pPDA-PMDA chains were easy to form crystal nucleus because of phase separation, based on which semi-rigid PMDA-ODA molecular chains began to crystallize.

以pPDA／ODA-PMDA型嵌段共聚酰亚胺薄膜为对象，借助TEM、SEM、PLM、超景深三维显微镜、TMA、WAXD等手段，研究结果表明：b-PI薄膜的拉伸强度、弹性模量均高于无规共聚酰亚胺薄膜；b-PI薄膜中形成了大量的微晶，这是由于刚棒状的pPDA-PMDA分子链段因相分离容易形成晶核，然后半刚性的PMDA-ODA分子链段以PMDA-pPDA为晶核进行晶体生长造成的，而且ODA-PMDA分子链的结晶和酰亚胺化反应基本上是同步进行的。
