Aptamer and gold nanorod-based fumonisin B1 assay using both fluorometry and SERS.
Article in Mikrochimica acta, 2020. 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
An aptamer-based assay is presented for the determination of fumonisin B1 (FB1). It is bimodal in that both surface-enhanced Raman spectroscopy (SERS) and fluorometry are applied for quantitation. It makes use of platinum-coated gold nanorod (AuNR) and DNA sequences. The complementary DNA of aptamer (cDNA) against FB1 is immobilized on the surface of AuNR. The aptamer of FB1 modified with Cy5.5 are complementarily hybridized with cDNA. In the absence of FB1, the aptamer and its cDNA associate. In this situation, strong SERS and weak fluorescence signals are obtained. In the presence of FB1, the aptamer disassociates with its cDNA and binds the target. As the concentration of FB1 increases, the SERS and fluorescence signal intensities of the mixture are gradually decreased and increased, respectively. Under optimized conditions, the SERS signal at 1366 cm
