Understanding DNA-encoded carbon nanotube sorting and sensing via sub-nm-resolution structural determination.
Article in Science advances, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 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
DNA has demonstrated the abilities to differentiate single-wall carbon nanotubes (SWCNTs) with various chiralities and manipulate their analyte sensing properties. However, the fundamental mechanisms underlying these remarkable abilities remain unclear due to the lack of high-resolution determination of DNA structures on SWCNTs. Here, we combine atomic force microscopy and single-particle cryo-electron microscopy to determine DNA structures on five different types of single-chirality SWCNTs, achieving unprecedented subnanometer resolution. This resolution enables the direct observation of left-handed helical DNA structures with pitches ranging from 1.59 to 2.20 nm, depending on the DNA sequence and nanotube chirality. These findings provide structural insights into the mechanisms by which DNA differentiates the chirality of SWCNTs, and governs the sensitivity, dynamic response range, and analyte differentiability of SWCNT sensors. We propose a non-Watson-Crick hydrogen-bonding network model, which not only accounts for the observed ordered DNA structures but also facilitates the design of DNA sequences for targeted SWCNT purification and desired SWCNT sensor performance.
