A Facile and Reproducible Method for the Purification of Peptide- and Protein-Functionalized DNA Nanostructures.
Article in JACS Au, 2025. 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
DNA nanotechnology has emerged as a promising field for biomedical applications, in both the therapeutic and diagnostic domains. The ability of DNA nanostructures to carry cargos in precise numbers and orientations makes them competitive candidates for drug delivery, biosensors, or imaging agents. Two of the main challenges for translating DNA nanostructures from the laboratory to the clinic are achieving cost-effective large-scale production and establishing comprehensive safety profiles. Having the ability to reliably and efficiently purify functionalized DNA nanostructures is key to both challenges and an open question in the field of DNA nanotechnology. Here we present a scalable method for the fast and efficient purification of a high concentration of peptide- or protein-functionalized DNA nanostructures. We use a gravity-driven size exclusion chromatography approach that has the potential to purify DNA nanostructures within 10 min in yields of up to 93% with purities of over 99.9% and is appropriate for both protein and peptide conjugates.
