Electron Optic Documents

Morphological observation is one of the important evaluations of substances. Morphology of biological specimens is often observed by optical microscopy, and a variety of information can be obtained by applying different staining or fluorescent labeling.

Since the scanning electron microscope (SEM) operates under vacuum, it is necessary to properly prepare a specimen in order to observe the biological specimen, and it is near-impossible to observe living organisms. However, in addition to observing the specimen surface at high magnification, by detecting various signals generated from the specimen, itis possible to obtain a lot of information by element analysis and other methods. Recently, methods for three-dimensional reconstruction and for observing waterdrops have been developed, and biological observation applications of SEM are becoming increasingly diverse.

We want you to know what SEM can do. We hope you will discover the microscopic beauty of the biological world. We hope that you will find this photo album we created as useful if you wish to observe biological samples in the future.
