Osmotically Tunable Microdroplets Enable Amplification-Free CRISPR Detection of Gene Doping.
Article in Advanced science (Weinheim, Baden-Wurttemberg, Germany), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Gene doping is an increasing challenge in sports, demanding highly sensitive and specific detection tools beyond the limitations of the current amplification-dependent methods. Here, an innovative amplification-free clustered regularly interspaced short palindromic repeats/CRISPR-associated protein (CRISPR/Cas) 12a assay integrated with osmotically tunable double emulsion (DE) droplets is reported for rapid and ultrasensitive gene doping detection. Target DNA and CRISPR/Cas12a complexes are encapsulated within DE droplets, where osmotic shrinkage rapidly concentrates the reaction components, thereby enhancing the fluorescent signal intensity without nucleic acid amplification. This platform enables the detection of the human erythropoietin (hEPO) gene at unprecedented attomolar levels within 30 min, achieving a 25-fold improvement in sensitivity compared with that of nonshrinkable formats. Notably, the assay demonstrated a robust and specific performance in complex serum samples with minimal matrix interference. This novel approach offers a rapid, reliable, and inherently contamination-free solution for gene doping surveillance with broad potential for versatile amplification-free nucleic acid diagnostics.
