Abstract
The present invention relates to a cryo-charging specimen holder for the electron microscope, particularly to a cryo-charging specimen holder for the electron microscope to hold various biological materials. The major feature of the invention is to charge the biological specimen and freeze the specimen at low temperature. The ice around the biological sample is also doped, so that after charging the doped ice surrounding the sample has a conductivity level comparable to that of conductor. Therefore, the sample can be embedded by the doped and charged ice obtaining the property of conductor, in order to be observed by the electron microscope.
