A facile method for fabricating nanochannels is presented. This method is based on mechanical wrinkling/folding of a stiff skin formed on a soft polymer, whereby the characteristic dimensions of the nanochannels are robustly tunable. Furthermore, the configuration of the nanochannels is switchable between open and closed. The tunable nanochannels can be exploited to trap and release nanoparticles “on demand”.
