Micro-Scale Arrays Fabricated on Parafilm and Polymethyl Methacrylate Towards Differential Colorimetric Analysis of Amines via Shape Transformation of Ag Nanoprisms.
Article in Analytical science advances, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
A novel micro-array was developed to a colorimetric detection of some amines, including histamine (HT), cadaverine (CAD), 1,4-diaminobutane (putrescine), 2-phenylethylamine (2-PEA), spermidine (SD) and ethylenediamine (EA) using silver nanoparticle (silver nanoprisms [AgNPrs]) as optical nanoprobe. This method relies on the chemical interaction between the TA-AgNPrs probe and candidate amines, resulting in observable colour changes. The interaction mechanisms were analysed using various techniques, including UV-visible spectrophotometry, naked-eye colorimetry dynamic light scattering spectroscopy and zeta potential measurements. The efficient interactions between the analytes and the optical probe are particularly observed at absorption conditions of 220-800 nm by a UV-visible spectrophotometry method. The designed chemosensor accurately detects various amines in the linear concentrations ranging of 1 µM to 50 mM. This analytical system has been successfully applied to analyse candidate amines in meat samples.
