1 · What the graph read from it

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.

2 · The registry

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

Noble metal nanostructures with real-time tunable plasmonic resonances have aroused wide research interest in the fields of materials science, physics, and chemistry. Among various engineering techniques for dynamic plasmonics, combining electrochromic polymers with plasmonic nanostructures is considered a significant strategy in constructing efficient dynamic plasmonic-based photonic devices. We demonstrate electrochemically depositing polyaniline (PANI) on gold nanoparticles (Au-NPs) to realize dynamic localized surface plasmon resonance (LSPR). To simplify the fabrication process, Au-NPs are obtained through thermal evaporation and the following annealing treatment. The dynamic plasmonic color switching is carried out through the electrochemically induced redox reaction of PANI. As a consequence, excellent switching performance on the plasmon resonance of Au-NPs is achieved through combining with electrochromic PANI. The PANI@Au-NP nanostructures show prominent reversibility over 50 switching cycles without distinct degradations, which is promising for a range of applications in optical devices, smart windows, and plasmonic chemical sensors.
