Through combining nanochannel technique and host–guest interaction, a universal tuneable nanofluidic diode is fabricated. By changing different azobenzene derivatives, the system can achieve replaceable surface charges, and realize the light and pH dual stimuli responses. The system has potential applications in fields such as photosensitive nanofluidic devices, light-controlled drug transport, pH-activated drug release and devices for optical information storage.
