超薄切片介绍

对样本开展研究时，为了以纳米级分辨率显示其精细结构，通常会使用到电子显微镜。电子显微镜有两种类型：扫描电子显微镜（SEM）用于对样本表面成像，以及需要使用极薄电子透明样本的透射电子显微镜（TEM）。因此，使用电子显微镜对样本内部的精细结构进行成像时，此类技术解决方案需要制作出非常薄的样本切片。被称为超显微技术的样本制备方法可以产生具有最小伪影的超薄切片（厚度20-150nm）。在切片过程中，样本的…

冷冻透射电子显微镜的投入式冷冻技术：基本原理

透射电子显微镜（TEM）所需的高真空度极大地减弱了研究自然存在于水相中的标本的能力：将“湿”标本暴露在远低于水蒸汽压的压力下，将导致水相在真空中迅速沸腾，对标本的结构造成破坏性后果。因此，在常规TEM中使用了各种方法在显微观察前干燥标本——这样一个样品制备步骤，通常导致实验结果出现假象。
