Rapid Detection and One-Step Differentiation of Cross-Reactivity Between Zika and Dengue Virus Using Functional Magnetic Nanosensors.
Article in ACS applied bio materials, 2021. 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
Infection with the Zika virus (ZIKV) is an ongoing problem especially as accurate, cost-effective testing remains unresolved. In addition, coinfection occurs with both the Dengue virus (DENV) and ZIKV which leads to cross-reactivity between the flaviviruses and can result in false positives and inaccurate testing. This supports the current need for a simple assay that can detect Zika antibodies sensitively that at the same time can differentiate between cross-reactive antibodies. In this study, we developed customizable magnetic relaxation nanosensors (MRnS) conjugated to various ligands, which included ZIKV (ZENV, zika domain III and NS1) and DENV proteins for specific detection of cross-reactive Zika and Dengue antibodies. Binding interactions between functional MRnS and corresponding targets resulted in the change in spin-spin magnetic relaxation time (T2MR) of water protons, allowing for a rapid and simple means by which these interactions were detected and quantified. Our results show the detection of Zika antibodies within minutes at concentrations as low as 20 nM and display high specificity, reproducibility, and analytical sensitivity. Furthermore, a mixture of functional MRnS was used for the one-step simultaneous detection and differentiation of Zika and Dengue infections. These results demonstrate high specificity and sensitivity for the detection of ZIKV and DENV despite coinfections in both simple and complex media. Overall, our magnetic nanoplatform could be used as a rapid and sensitive assay for the detection of not only Zika- and Dengue-related testing but can be further applied to serological samples of any other pathogens.
