Observation of biological alive samples is one of the biggest dreams of electron microscopy. However, biological samples are commonly chcmically fixed and dried, sputter-coated on their surfaces with thin conductive film or rapidly frozen, and observed by electron irradiation under vacuum in the conventional transmission electron microscopes (TEMs) or scanning electron microscopes (SEMs). For overcoming the problem of charging and approaching the possibility to observe samples in their nature state, scientists have tried to use a gas environment in electron microscopes such as environmental scanning electron microscopc (ESEM), and many results of samples observation in various environmental atmospheres were reported. Unfortunately, they have not succeeded in the observing biological specimens alive.
