85:, the damage can be dissolved away , revealing the ionization damage. The greater the damage, the faster is the etching. The technique has been used in a number of applications. On the one hand, inspection of the tracks is a valuable tool in determining properties of charged particles as e.g. cosmic rays. On the other hand, the number of such tracks in natural glasses and minerals can be used for
96:, widely used in microbiology. To create nucleopore filters, the technique is applied to a polycarbonate film and the etching is allowed to continue from both sides of a sheet of plastic until the two holes are connected, resulting in a tiny hole in the sheet. Continuous dissolving thereafter slowly and predictably widens the hole diameter until the desired diameter is obtained.

Use of the technique in an experiment carried by a high-altitude balloon in 1975 resulted in the detection of one highly anomalous cosmic ray particle that traversed a stack of 32 sheets of Lexan plastic. The particle was tentatively identified as a
