Stimulus-responsive track pores

Abstract
Ion track grafting enables the manufacture of chemically responsive track pores analogous to the discrete membrane channels found in biology. For this purpose etched ion tracks generated in CR-39 are surface-grafted by methacryloyl-L-alaninemethylester. In the future, the responsive track pores could be used to model the actively controlled channels in biomembranes and may lead to interesting technological applications.
