Development
of a multifunctional sensor is highly desirable. In
this work, traces of a carcinoid cancer biomarker of 5-hydroxyindole-3-acetic
acid (5-HIAA) in real human urine can be detected by lanthanide nanoparticle Eu-CFC (CFC = 7-chloro-1-cyclopropyl-6-fluoro-4-oxo-1,4-dihydroquinoline-3-carboxylic
acid) and the sensing devices of the test paper and agarose gel, achieving
an ultralow LOD of 0.8 × 10–3 ppm within a
sensing time of 2.0 min. Interestingly, by metal center regulation
of Tb and Eu codoping, nanoparticle TbEu2-CFC shows high-sensitivity and low-LOD (0.019%
v/v) sensing of water in ethanol. The sensing mechanisms are revealed
by both experiments and quantum chemical studies.
