Dopamine fast determination in pharmaceutical products using disposable printed electrodes modified with bimetal oxides carbon nanotubes nanocomposite.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
Dopamine is an essential neurotransmitter involved in the regulation of our pleasure, motivation, and other biological functions. Thus, tracking and monitoring the biological dopamine level is crucial for the rapid and effective treatment as well as for the diagnosis of the neurodegenerative and neurological disorders. Nanostructured electrochemical systems are tested and validated as promising methods for dopamine detection. In this study, carbon nanotube-anchored bimetallic manganese/copper bi-oxides nanocomposite-modified screen-printed carbon electrodes (Mn/Cu oxides @CNTs-SPCEs) were exploited for the electrocatalytic oxidation and direct determination of dopamine. From the morphological analysis, the particle size of the bimetallic oxides spherical nanoparticles was ranged from 9.0 to 45 nm, while the electrocatalytic activity of nanocomposite towards dopamine oxidation was examined by cyclic voltammetry (CV) and differential pulse voltammetry (DPV) to demonstrate the acquired high sensitivity and selectivity. The optimized DPV assay provided a wide linear dynamic range of dopamine concentrations (from 0.001 to 140 µM), and a low detection limit of 0.3 nM. Eventually, the newly modified electrochemical method was applied for dopamine detection in pharmaceutical products with high accuracy.
