Detection of Ferric Ion by Fluorescent Carbon Nano Dots Synthesized from Forsythia Residue.
Article in Journal of fluorescence, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
To fully utilize the wastes of the traditional Chinese herbs, a highly functionalized fluorescent carbon nano dots (CDs) based ferric ion sensor was prepared from forsythia residue via a one-step hydrothermal method. Under transmission electron microscope (TEM), the CDs were observed to be spherical with the diameter in the range of 5-20 nm. Comprehensive analyses documented the CDs' favorable morphology, diverse functional groups, high water solubility, remarkable optical properties, and exceptional stability under various environmental conditions. Moreover, the CDs exhibited good optical properties with vivid green photoluminescence (PL) when they were exposed to ultraviolet (UV) light. Furthermore, the prepared CDs demonstrated selective fluorescence quenching behavior towards ferric ions with satisfactory sensitivity and a low limit of detection (LOD) of 4.3 µM. Additionally, the CDs displayed good selectivity towards Fe
