Abstract:
Design and fabrication of smart switchable nanofluidic diodes remains a challenge in the life and materials sciences. Here, we present the first example of a novel Zn(2+)/EDTA switchable nanofluidic diode system based on the control of one-side of the modified hourglass-shaped nanochannel with salicylaldehyde Schiff base (SASB). The nanofluidic diode can be turned on in the response of Zn(2+) and turned off in response to EDTA solution with good reversibility and recyclability.
