title: An ion-gating multinanochannel system based on a copper-responsive self-cleaving DNAzyme.
abstract: We developed an ion-gating nanochannel composite system by immobilizing a Cu(2+)-responsive self-cleaving DNAzyme into PET conical multinanochannels, which could control the ion transport by regulating the surface charge density of the channels.
