A Perylene-Based Bright Red-Emitting Probe for Wash-Free Cell Plasma Membrane Imaging Via Excimer Formation.

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
Excimer emission exhibits red-shifted, broadened, and large Stokes-shifted characteristics compared to monomeric emission, making it advantageous for biological imaging. In this work, a perylene-based amphiphilic fluorophore (DAVP) was developed for wash-free cell plasma membrane imaging. DAVP readily forms excimer, emitting intense red fluorescence. In water, it shows very weak fluorescence, but its emission intensity significantly increases upon molecular aggregation induced by either increasing concentration or adding THF to aqueous solutions. Notably, DAVP exhibits enhanced fluorescence in cationic and anionic surfactant micelles compared to its aggregated states. Leveraging these properties, DAVP serves as a membrane-specific imaging agent with several distinct advantages: bright red emission, a large Stokes shift, high water solubility, low cytotoxicity, rapid staining, and wash-free capability.
