Purification of DNA Nanoparticles Using Photocleavable Biotin Tethers.
Article in ACS applied materials & interfaces, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
The number of applications of self-assembled deoxyribonucleic acid (DNA) origami nanoparticles (DNA NPs) has increased drastically, following the development of a variety of single-stranded template DNA (ssDNA) that can serve as the scaffold strand. In addition to viral genomes, such as M13 bacteriophage and lambda DNAs, enzymatically produced ssDNA from various template sources is rapidly gaining traction and being applied as the scaffold for DNA NP preparation. However, separating fully formed DNA NPs that have custom scaffolds from crude assembly mixes is often a multistep process of first separating the ssDNA scaffold from its enzymatic amplification process and then isolating the assembled DNA NPs from excess precursor strands. Only then is the DNA NP sample ready for downstream characterization and application. In this work, we highlight a single-step purification of custom sequence- or M13-derived scaffold-based DNA NPs using photocleavable biotin tethers. The process only requires an inexpensive ultraviolet (UV) lamp, and DNA NPs with up to 90% yield and high purity are obtained. We show the versatility of the process in separating two multihelix bundle structures and a wireframe polyhedral architecture.
