Fluorescent Biofunctionalized Silver and Gold Nanoparticles: Bright Tools for Bioimaging Applications.
Article in ACS omega, 2026. 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
The aim of this work is to evaluate different nanostructured systems based on noble metal nanoparticles suitable for drug delivery and release related to the treatment of multiple sclerosis. To this end, four different systems are thoroughly characterized from a chemical-physical and structural perspective and, then, from a biological perspective. Gold and silver nanoparticles were synthesized and stabilized with different biocompatible ligands, including poly-(ethylene glycol), citrate, and cysteine, to modulate their colloidal stability and surface reactivity. UV-Vis spectroscopy revealed characteristic plasmonic absorption bands at about 400 nm for silver and nearly 550 nm for gold nanoparticles. Morphological analyses, performed by Transmission Electron Microscopy, and colloidal stability, studied by Dynamic Light Scattering, highlighted differences in size distribution and polydispersity among the systems. The nanoparticles were subsequently functionalized with fluorescein isothiocyanate, a fluorescent dye, to enable their detection and tracking within cells using an accessible analytical technique appropriate for the study of immune cells, such as flow cytometry. Nanoparticle surface properties were thoroughly investigated by means of Fourier-transform infrared, synchrotron radiation-induced X-ray photoelectron, and near edge X-ray absorption fine structure spectroscopies. Flow cytometry analyses demonstrated efficient nanoparticle-cell interaction with peripheral blood mononuclear cells, and a cell viability assay performed with the improved system highlighted the potential for applications in drug delivery and bioimaging.
