An ultrasensitive 2,4,6-trinitrophenol nanofluidic sensor inspired by olfactory sensory neurons in sniffer dogs.

ABSTRACT: Explosives, as high-energy materials, could generate huge destructive explosions along with a massive release of energy. The regulatory or illegal transportation of explosives threatens the peace and stability worldwide. Among the many high-powered explosives, 2,4,6-trinitrophenol (TNP) is not only frequently used in many terrorist attacks, but also seriously jeopardizes environmental safety and human health. Hence, dependable methods for high-sensitivity, rapid and portable detection are desperately needed. Inspired by olfactory sensory neurons (OSNs) in sniffer dogs, we present a nanofluidic sensor for ultrasensitive TNP detection by in situ growing dense UiO-66-NH₂ layers on the surface of anodic aluminum oxide (AAO) nanochannels. TNP could be specifically captured by
