Prism coupling and visualization of surface nanoscale axial photonic structures.
Article in Communications engineering, 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
Surface nanoscale axial photonics (SNAP) has demonstrated the record subangstrom precise fabrication of miniature optical devices enabling applications in classical and quantum signal processing unfeasible to date. However, SNAP devices formed by subnanometre protrusions of the optical fiber surface lack robustness and simple identification methods. This complicates their controlled alignment and raises concerns about their practical applicability. Here we introduce techniques that enable both direct visualization of nanoscale SNAP features and efficient coupling to fused-silica SNAP microresonators using evanescent-field prism couplers. These advances provide precise control of light-resonator interactions and establish a scalable and robust route towards on-chip integration of SNAP devices, opening opportunities for their critical applications in computing, telecommunications, ultraprecise sensing, and fundamental optical science.
