  This paper reviews opportunities for using electron microscopy in various gas
atmospheres for the analysis and morpho-physiological modification of
biological structures. The approaches that allow varying the gaseous phase
content, as well as temperature, humidity, and pressure, are considered. The
applicability of both kinetic and dynamic approaches to the tissue and
bioinorganic structure manipulations is pointed out. The possibility of
simulation of the beam-induced formation and disintegration of abiogenetic
molecular structures is also mentioned as a particular case of the electron
beam influence and treatment of the precursor medium in an artificial
atmosphere.
