离子刻蚀技术在扫描电镜样品制备中的应用已引起广泛注意。经离子刻蚀后既可清除样品表面的污染,揭示其表面的超微结构,又可获得样品的内部结构信息。近年来我们对几个医学生物样品作了离子刻蚀后在扫描电镜下观察,并取得了较满意的结果。 The application of ion etching technology in the preparation of SEM samples has attracted a lot of attention. After ion etching can remove the surface contamination of the sample, reveal the surface of the ultrastructure, but also access to the internal structure of the sample information. In recent years, several medical biological samples were ion-etched and observed under a scanning electron microscope. Satisfactory results were obtained.
