众所周知，使用透射电子显微镜（TEM）的分析产生非常高分辨率的薄样品的图像。然而，TEM分析的适用性并不普遍，因为需要高的内部真空。这种高真空排除了对活体样品或在气体或液体环境中的样品的TEM研究。为了解决这一问题，L。比利时布鲁塞尔自由大学的Marton于1935年第一个设计出环境电池（E-cell），该电池密封在TEM样品保持器的尖端[1]。Marton的设计包括两个0.5 μm的铝箔作为上下窗口，用于包裹生物样品以维持生存环境。电子透明窗口允许在TEM模式下对受限的生物对象进行成像。从那时起，环境TEM（E-TEM）越来越受到生物科学家的关注，最终也受到材料科学家的关注。
It is well known that analysis using transmission electron microscopes (TEM) yields very high resolution images of thin specimens. However, the applicability of TEM analysis is not universal due to the requirement that a high internal vacuum is required. This high vacuum precludes the TEM study of living specimens or specimens in a gas or liquid environment. In order to tackle this problem, L. Marton of Universite Libre in Brussels, Belgium was the first to design an environmental cell (E-cell) in 1935 that was sealed in the tip of a TEMsample holder [1]. Marton's design included two 0.5 μm aluminum foils as upper and lower windows sandwiching a biological sample to sustain a living environment. The electron transparent windows permitted the confined biological objects to be imaged in TEMmode. Since then, environmental TEM (E-TEM) has received increasing attention from biological scientists and eventually from materials scientists as well.
