title: Calcein-modified multinanochannels on PET films for calcium-responsive nanogating.
abstract: Calcein-modified multiporous films with conical channels are introduced in a nanofluid device to enhance the calcium-responsive intensity and stability of ionic currents. Calcein with more carboxyls enhances the response of channels to calcium ions, and the capability of immobilized calcein for Ca(2+)-binding could be regulated by the deprotonation of these carboxyls.
