From: Role of outer surface probes for regulating ion gating of nanochannels
High-efficiency ion-gating systems probed by dual-current readout. a Schematic of IT (dashed gray arrow) and ET (dashed blue arrow) through double labeling, ATP-responsive, DNA SS-based biomimetic nanochannels. Shown here is the disassembly process at the inner of nanochannels. b–d SWV curves of the assembled DNA SS and the disassembly by ATP at different regions of AAO nanochannels. e Comparison of EC signals changes at the DNA SS-based ATP recognition events. f–h I–V traces of the assembled DNA SS and the disassembly by ATP at different regions of AAO nanochannels. i Comparison of IC signals changes at the DNA SS-based ATP recognition events. Error bars represent standard deviations of independent triple experiments
