A biomimetic nanofluidic diode based on surface-modified polymeric carbon nitride nanotubes

A controllable ion transport including ion selectivity and ion rectification across nanochannels or porous membranes is of great importance because of potential applications ranging from biosensing to energy conversion.Here, a nanofluidic ion diode was realized by modifying ut solution gel for cats carbon nitride nanotubes with viseart etendu cashmerie different molecules yielding an asymmetric surface charge that allows for ion rectification.With the advantages of low-cost, thermal and mechanical robustness, and simple fabrication process, carbon nitride nanotubes with ion rectification have the potential to be used in salinity-gradient energy conversion and ion sensor systems.
