Real-time 3D monitoring of NIR laser effects on biodegradable polymers.
Article in Scientific reports, 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
We present the real-time 3D monitoring of NIR laser exposure effects on biodegradable Starch/Kefiran/ZnO nanocomposites polymers using a compact and robust digital holographic microscopy (DHM) arrangement in transmission mode. These biodegradable nanocomposites are of particular interest for food packaging due to their antimicrobial activity and extended shelf-life performance. Our DHM approach facilitates precise 3D imaging, allowing for the detailed observation of subtle structural changes being induced by NIR exposure. Through systematic reconstruction of the recorded digital holograms, we quantify the morphological response of the biopolymers and the local temperature variations within them. Our results reveal that NIR exposure smooths the nanocomposite surface through thermally driven morphological rearrangement, which may enhance the film's hydrophilicity and thereby increase its susceptibility to environmental degradation pathways. This integrated DHM-NIR platform offers a promising bench-top tool for in situ analysis of microstructural and thermal dynamics in a wide spectrum of materials.
