Chemical etching of track polymer structures for biosensors

Original language description

In general, etching of two identical ion-irradiated polymer foils in the same vessel with the same etchant for the same times does not lead to identical track shapes in both foils. For contrast, the track shapes, the etching speeds and consequently also the etchant consumption of the two foils diverge increasingly with increasing etching times, unless this is prevented by forceful external equilibration of the system. This tendency towards divergence of a system of multiple ion tracks originates from its lack of self-synchronization during etching. A theory has been developed for this case that also shows general applicability to other diverging effects. This finding can be explained by slight statistical differences of the two foils as concerns both their structural uniformity and their different etchant consumptions. The application of standard track etching techniques inevitably leads to an increasing competition of both foils for etchant consumption and track dissolution, hence to increasingly diverging etching speeds. The underlying physical reason behind all these effects is the absence of self-synchronization in the considered systems which make them increasingly disordered. A computer model has been created to study the passage of ion flows through cylindrical nanopores that mimic etched ion tracks in modern biosensors. Such cylindrical nanopores are created by ion implantation of thin films. Subsequent chemical etching of the films is a necessary step in creating a biosensor device. The developed theory for chemical etching of track polymer structures is important for creating new track biosensor systems with controllable characteristics.
