Fluorescent Metal-Organic Framework Nanoparticles for Explosive Detection.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Fluorescent metal-organic framework (MOF) nanoparticles were prepared by doping zeolitic imidazolate framework-8 (ZIF-8) with fluorescein through ″one-pot″ synthesis. The resulting fluorescein@ZIF-8 (F@ZIF-8) material exhibits a luminescent "turn-off" response toward nitroaromatic explosives. We performed a combined experimental and computational study to understand the structural properties and formation mechanisms of the prepared F@ZIF-8 composite and to explain the solid-state fluorescence and quenching in the presence of a nitroaromatic analyte. We confirmed that fluorescein can be encapsulated within the ZIF-8 cages through electrostatic interactions between dianionic fluorescein and Zn open metal sites. The scaffold of ZIF-8 can reduce the aggregation-caused quenching (ACQ) effect of fluorescein and increase the quantum yield to 69.7 ± 0.1%. The photophysical mechanism explains the fluorescence emission of F@ZIF-8 in the solid state and the fluorescence quenching in the presence of nitroaromatic analytes, including 2,4,6-trinitrophenol (TNP), trinitrotoluene (TNT), 4-nitrotoluene, nitrobenzene, and 2-nitropropane. Our material exhibits a high sensitivity toward TNP with a limit of detection (LOD) of 2 μM. This work presents a new opportunity for designing luminescent porous materials for "signal-off" sensing and demonstrates the potential of using luminescent MOFs as an analytical tool for explosive detections.
