[Use of atomic force microscopy to study the morphology and structure of viruses].
The paper describes AFM methodic approaches in the investigation of viruses (TMV, phage T4). A possibility is shown to use this method to obtain high-quality three-dimensional image of objects without additional treatment with salts of heavy metals. The phage T4 was also a model to study the object density, using the phase shift of the AFM. Such researches can determine the internal structure of a virion and folding of nucleic acid inside a virion.
