Comparative Optical Response of DNA-Natural and Synthetic Food Colorant Systems.
Article in Polymers, 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
Biopolymers functionalized with chromophores exhibit interesting optical properties with a high potential for applications in photonics. Quinoline yellow (QY), sunset yellow (SY) and riboflavin (RB) are commonly used as colorants in the food industry, which makes them suitable candidates for the development and manufacture of environmentally friendly devices for integrated photonics. The incorporation of these dyes into a deoxyribonucleic acid (DNA) matrix could significantly contribute to enhance the optical response and sensitivity of the obtained composites. This enhancement is mainly due to the interaction between the conjugated π-electrons from the aromatic groups of the chromophores and the DNA matrix. Also, it may influence the appearance of interesting molecular structural arrangements and modify the local electronic environment. The linear optical analysis was performed by UV-Vis, fluorescence and Fourier transform infrared (FTIR) spectroscopies. At the same time, the pump-probe interferometric method was used to study the light-induced refractive index modification.
