GenericFixationforElectronMicroscopy
Generic Fixation for Electron MicroscopyThe best way to fix a sample for electron microscopy is to follow a procedure developed and proven by others. If this is not possible, this method will produce good fixation for most tissues.Solutions:100 mM PIPES, pH 7.0-7.4 or 50 mM Cacodylate, pH 7.42 mM MgSO40.25 M sucrose1-2.5% glutaraldehyde50 mM Cacodylate, pH 7.4 (note: cacodylate contains arsenic, so handle carefully)1......阅读全文

EBSD分析(electron-backscatter-diffraction)是指
EBSD即电子背散射衍射。EBSD的原理始于20世纪50年代,技术问世于80年代。EBSD是扫描电子显微镜(SEM)的一个标准分析附件,但大大拓宽了扫描电子显微镜进行微观分析的功能。它可以与SEM的其他功能(包括EDS等配件)结合起来,原位成像、成分分析、大样品分析、粗糙表面成像等,克服了传统分析方
光合电子传递-(photosynthetic-electron-transport)
光合作用中,受光激发推动的电子从 H2 O到辅酶Ⅱ( NADP )的传递过程。光合色素吸收光能后,把能量聚集到反应中心——一种特殊状态的叶绿素 a分子,引起电荷分离和光化学反应。一方面将水氧化,放出氧气;另一方面把电子传递给辅酶Ⅱ( NADP ),将它还原成 NADPH,其间经过一系列中间(电

补体结合反应(complement-fixation-test)技术概况
可溶性抗原,如蛋白质、多糖、类脂质和病毒等,与相应抗体结合后,抗原抗体复合物可以结合补体,但这一反应肉眼不能察觉,如再加入红细胞和溶血素,即可根据是否出现溶血反应来判定反应系统中是否存在相应的抗原或抗体。这个反应就是补体结合反应。 补体结合反应是一种古老的血清学技术,Bordet和Gengou在19

如何通过透射电子显微镜(TEM)初步确定待测样品
束1. 选区电子衍射(selected area electron diffraction): 判断样品的晶体结构,晶格常数,点阵应变等。通常需要结合X射线衍射来综合判断。但选区电子衍射的选区范围最小只能达到~200 nm。这主要是来自物镜像差的限制。现在前沿的技术是纳米电子微区衍射(Nanobea
扫描电子显微镜(Scanningelectron-microscopy,-SEM)
扫描电镜分析可以提供从数纳米到毫米范围内的形貌像,观察视野大,其分辩率一般为6纳米,对于场发射扫描电子显微镜,其空间分辩率可以达到0.5纳米量级。其提供的信息主要有材料的几何形貌,粉体的分散状态,纳米颗粒大小及分布以及特定形貌区域的元素组成和物相结构。扫描电镜对样品的要求比较低,无论是粉体样品还是大
原子力显微镜(Atomic-Force-Microscopy-,简称AFM)
原子力显微镜的工作原理就是将探针装在一弹性微悬臂的一端,微悬臂的另一端固定,当探针在样品表面扫描时,探针与样品表面原子间的排斥力会使得微悬臂轻微变形,这样,微悬臂的轻微变形就可以作为探针和样品间排斥力的直接量度。一束激光经微悬臂的背面反射到光电检测器,可以精确测量微悬臂的微小变形,这样就实现了通过检
