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

A controlled method to prepare glutathione-protected bimetallic gold-platinum nanoclusters (Au-PtNCs) has been established. The Au-PtNCs show either strong red (625 nm) or near-infrared (NIR, 805 nm) emission. Further characterizations indicated that the average particle size grows from 1.42 to 1.78 nm, the larger particles being responsible for the redshift of emission. The NIR emitted Au-PtNCs are applied as a novel ratiometric probe of Ag(I), which induces a new emission peak at ~635 nm and quenches the initial emission gradually. The determination shows very high selectivity toward Ag(I) among other metal ions. A limit of determination (10 nM) and the linear range (0.10 to 15 μM) are achieved, which is much lower than the EPA mandate of 0.46 μM for Ag(I) in drinking water. The response mechanism is attributed to the fact that the added Ag(I) has been reduced by the core of Au-PtNCs and deposited on the surface, which induces new fluorescence emission around 635 nm. In addition, the ratiometric method is feasible for Ag(I) determination in serum serum with good recovery (between 98.3% and 102.0%, n = 3), showing very high application potential. The present study provides a controlled method to prepare Au-PtNCs with strong red and NIR emission and supplies a novel NIR ratiometric probe of Ag(I). Schematic presentation of the controlled preparation of glutathione-protected bimetallic gold-platinum nanoclusters (Au-PtNCs) with either red or near-infrared (NIR) emission, and application in ratiometric detection of Ag(I) with high selectivity and sensitivity.
