Excitation Wavelength Optimization of Europium-Doped Carbon Dots (Eu-CDs) for Highly Sensitive Detection of Tetracyclines in Water.

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
Antibiotic contamination of water bodies has become a serious problem, which leads to aquatic life pollution and the development of antibiotic resistance. Hence, development of highly sensitive and selective optical sensors for antibiotic detection is at the forefront of scientific research. In this study, we present the synthesis of europium-doped carbon dots (Eu-CDs) and excitation wavelength optimization for the highly sensitive detection of tetracycline (TC) and TC-family antibiotics in water. An extensive physicochemical analysis and excitation wavelength optimization reveal that Eu-CDs can yield an exceptionally high limit of detection of TC at ∼5.8 nM over a linear range of 0.01-3 μM. Selectivity analysis with other common antibiotics revealed that the produced Eu-CDs are highly sensitive to TC and TC-group antibiotics only. A plausible mechanism for excitation-dependent TC detection by Eu-CDs is proposed. We firmly believe that the prepared Eu-CDs can be potentially employed for quick and sensitive monitoring of TC-family antibiotics in water samples.
