Lanthanide ion-based metal-organic framework as an effective tri-mode nanoprobe for alcoholic content detection.

A lanthanide ion-based metal-organic framework (Eu-TATAB nanorods) was designed and synthesized as an effective tri-mode nanoprobe for sensitive and portable detection of ethanol content in a water-ethanol mixture. The assay was based on the responsive properties of Eu-TATAB nanorods to ethanol stimulus and their adaptive encapsulation capability towards optically active lanthanides. With the addition of ethanol to the Eu-TATAB nanorods, the structure was destroyed, resulting in a decrease in luminescence, electrochemiluminescence, and ultraviolet-visible spectrophotometric signals by perturbing energy transfer in the Eu-TATAB nanorods.
