Influence of Gold Nanoparticles on eNOS Localization in Gill Tissues: Advancements in Immunofluorescence Techniques.
Article in ACS omega, 2024. 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
This study optimizes immunofluorescence techniques using gold nanoparticles (AuNPs) to improve visualization of endothelial nitric oxide synthase (eNOS) in gill tissue. Two types of AuNP dispersions, stabilized in phosphate buffered saline (PBS) and citrate buffer (CB), were evaluated for their imaging performance. AuNPs suspended in PBS provided significantly better optical contrast due to uniform distribution and effective tissue attachment, whereas citrate-suspended AuNPs exhibited aggregation, resulting in reduced contrast. These results highlight the influence of suspension media on AuNP performance, particularly in balancing fluorescence signals to improve contrast. The PBS suspension allowed clearer visualization of eNOS, highlighting the role of AuNP compatibility in improving immunofluorescence results. This study highlights the importance of strategic selection of AuNP dispersions in contrast agent design and provides insights for advanced imaging applications where sensitivity and accurate localization of biomolecules are essential. By refining the use of AuNPs as contrast enhancers, this approach offers potential improvements in bioimaging accuracy, facilitating more precise visualization in complex tissue environments.
