A Comparative Study of Conductive 3D Printing Filaments for Electrochemical Sensing Applications Pretreated by Alumina Polishing, Electrochemical Activation, and Electrodeposition of Au Nanoparticles.
Article in ACS electrochemistry, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
3D-printed electrochemical devices have gained tremendous attention recently because they are highly customizable platforms for analysis and energy storage that can be produced using simple, inexpensive components in a wide variety of settings. 3D-printed electrochemical sensors, fabricated from carbon-loaded conductive thermoplastics, enable decentralized production of electrochemical devices that, if optimized, could be widely distributed. Achieving this goal requires a comprehensive understanding of the electrochemical behavior of these filaments. Here, we investigated how the electrochemical behavior of three commercial filaments was affected by alumina polishing, electrochemical activation in 0.5 M NaOH, and electrodepositing Au nanoparticles (NPs). The goal of this study is to characterize if/how these commonly used pretreatments affect different filaments. The study is not an exhaustive combination of all filaments and pretreatment options. We characterized the physical properties of each filament/pretreatment using thermogravimetric analysis, scanning electron microscopy, and Raman microscopy measurements. We then benchmarked the background electrochemical processes (capacitance and solvent window), the peak current response versus scan rate, and the peak potential separation of two common outer-sphere redox species (ruthenium hexamine and ferrocene methanol) for each filament under each pretreatment (
