Hybrid DNA Origami - Graphene Platform for Electrically-Gated Nanoscale Motion.
Article in Advanced materials interfaces, 2025. 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
We present a proof-of-principle device for axial high-resolution operation that combines a deoxyribonucleic acid (DNA) origami with a functionalized graphene layer, analyzed by nanoscopy. Along the DNA origami structure, we bind ATTO-488 fluorophores at specific distances from graphene, from where we expect specific fluorescence lifetime values due to nearfield energy transfer processes. These are characterized by Fluorescence Lifetime Imaging Microscopy (FLIM). Through modulation of the electrostatic potential of graphene under electrical gating, we observe changes in the fluorescence lifetimes. These are understood as the result of changed energy transfer coupling conditions between the fluorophore and graphene's electronic states, combined with a vertical displacement of the DNA origami structure that matches molecular dimensions. We provide a hybrid architecture whose nanoscale operation depends on the applied voltage regime. A potential application of these findings may be envisioned for biocompatible sensing approaches, in medical or environmental sensing.
