Interfacial Engineering of Dual-Layer Au-Shelled Ag Nanowires: Decoupling Chemical Stability From Ultrasensitive Surface-Enhanced Raman Spectroscopy Activity.
Article in Small science, 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
One-dimensional (1D) silver nanowires are promising surface-enhanced Raman spectroscopy (SERS) substrates, yet their plasmonic hotspots are spatially confined to sharp tips or junctions, leaving the extensive body optically inactive. Additionally, realizing high-performance Ag-based substrates faces a fundamental trade-off between chemical stability and surface activity. To simultaneously resolve these geometric and chemical limitations, we present a stepwise interfacial engineering strategy to synthesize 3D hierarchical dual-layer porous@smooth Au-shelled Ag nanowires. This architecture decouples functional requirements: A hermetic smooth Au inner shell passivates the Ag core for long-term stability, while the nanowire body serves as a structural scaffold for a porous Au outer shell. This design activates the entire 1D surface, creating a volumetric distribution of high-density hotspots localized at the interparticle gaps. Consequently, the hierarchical nanowires exhibit exceptional sensitivity for model analytes, including malachite green, crystal violet, and methylene blue, with detection limits ranging from 10
