The model was constructed using the classical molecular dynamics (MD) method. The processes of the passage of ion streams through nanotracks are the basis for the functioning of track biosensors. In the creation of track structures, chemical etching plays an important role. At this stage of the work, it was shown that using computer modeling it is possible to study the mechanisms of chemical etching of track structures. Simultaneously, it becomes possible to obtain new information about the real structure of the ion-induced nanotrack. This research uses a computer model for the passage of ion streams through cylindrical nanopores that simulate etched ion tracks in modern biosensors. There are two ways of modification the defective structure of nanotracks. The first way requires taking into account the mechanisms of interaction of fast ions with the film material during the formation of tracks. The second one requires special chemical etching. Chemical etching plays an essential role in the creation and research of a track biosensor. First of all, the formation of the primary track requires the action of a certain herbalist to prevent the healing of the ion-induced ordered space of the film. But etching can be used to investigate the defect structure of the region adjacent to the track. Such a study can be carried out using a computer simulation of a track filled with matter passing through the track. So far, it has been established that the track wall has a three-layer structure. The first layer, closest to the track, is the most ordered, the second layer (Penumbra) is less ordered and and onwards the structure of volume.
