Nanopore Label-Free Monitoring of B-DNA and Z-DNA Conformational Transition in Real Time.
Article in ACS nano, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
The transition from right-handed B-DNA to left-handed Z-DNA represents one of the most dramatic structural changes in biology and plays a crucial role in gene expression and transcription. Monitoring this transition is essential for understanding fundamental biological processes, elucidating disease mechanisms, and developing more effective therapeutic strategies. Here, we present a label-free approach to distinguish between Z-DNA and B-DNA by detecting changes in the electrical current modulations as they translocate through a nanopore. This method enables real-time monitoring of B-to-Z and Z-to-B transitions and studying reaction kinetics at the single-molecule level. By directly capturing dynamic structural changes in DNA, our nanopore platform offers a powerful way to investigate DNA structural mechanics and study its interactions with small molecules or therapeutics, thereby advancing the development of versatile tools for studying biologically relevant DNA conformational switches with potential biotechnological applications.
