Eu(III)-Functionalized MOF-Based Dual-Emission Ratiometric Sensor Integrated with Logic Gate Operation for Efficient Detection of Hippuric Acid in Urine and Serum

Inorganic Chemistry, Journal Year: 2023, Volume and Issue: 62(6), P. 2715 - 2725

Published: Jan. 27, 2023

With the introduction of Eu3+ ions as secondary fluorescent signal reporter and sensing active sites, a dual-emission ratiometric sensor Eu3+@NiMOF (Eu3+ functional NiMOF) for hippuric acid (HA) detection in urine serum was fabricated via postsynthetic encapsulating strategy. Based on two emission signals at 441 nm (turn-on) 628 (turn-off), produced provided enhanced sensitivity, higher selectivity, 9.7 times lower limits (LOD) HA (2.38 μM, 0.42 μg·mL-1) than that pristine NiMOF. Considering high sensitivity visualization results, further exploration intelligent applications process carried out by constructing tandem combinational logic gate to improve practicability convenience with help smartphone. This work provides promising approach developing MOF-based sensors detect biomarkers.
