An ICT-FRET Fluorescent Probe Derived from Coumarin-Naphthalimide for Ratiometric Detection of Copper Ions.

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
This research presents a new ratiometric fluorescent probe designed for Cu²⁺ detection, utilizing a dual mechanism of intramolecular charge transfer (ICT) and fluorescence resonance energy transfer (FRET). In this probe, coumarin acts as the energy donor while naphthalimide serves as the acceptor, with a 2-picolinic ester moiety functioning as the Cu²⁺ binding site. In the absence of Cu²⁺, the 2-picolinic ester effectively suppresses electron transfer, inhibiting both ICT and FRET, resulting in strong blue fluorescence (λem = 478 nm) from the coumarin moiety. However, upon Cu²⁺ binding, the Cu
