1 · What the graph read from it

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.

2 · The registry

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

Nanoconfinement as observed in natural (e.g. green fluorescent protein, GFP) or artificial (metal-organic or covalent organic frameworks) systems effectively modulates chemical and physical properties of encapsulated molecules for various photonic, electronic, or catalytic applications. Inspired by GFP's barrel-like peptide scaffold, which stabilizes the chromophore within a confined space, here we develop photobleaching-resistant super-resolution DNA framework (SDF) dots that enables programmable confinement of various types of fluorophores within the inner cavity resembling GFP. We find that SDF dots are resistant to reactive oxygen species-induced photobleaching due to the shielding effects of DNA frameworks. SDF dots with four fluorophores labeling inside of the cavity leads to ~1.8-fold enhancement in photostability compared to the corner labeling, whereas ~50-fold enhancement compared to single fluorophore labeled on double-stranded DNA. These ultrastable SDF dots are readily adaptable for super-resolution imaging including stimulated emission depletion (STED) and structured illumination microscopy (SIM) imaging. We realize STED imaging of live cell membranes over 30 min. We further construct ultrastable super-resolution SIM barcodes that can distinguish eighteen colored barcodes with a spatial resolution of ~70 nm. This strategy provides a versatile platform for engineering ultrastable fluorescent probes for advancing super-resolution imaging and single-particle tracking in biophysics and biomedical research.
