DNA Logic-Integrated Quantum Nanosensor for MicroRNA Diagnostics.
Article in JACS Au, 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
Nanodiamonds (NDs) with nitrogen-vacancy (NV) centers are emerging as powerful quantum nanosensors (QNs) in biomedical applications due to their exceptional sensitivity. However, achieving optimal diagnostics performance necessitates both high sensitivity and selectivity; especially in practical biomedical settings, it remains challenging for QNs to provide quantitative analyses when multiple analytes are present. Here, we present a biosensing platform that integrates DNA logic gates (DLGs) with spin-based quantum sensing, termed DLG-QN for ultrasensitive and ultraselective diagnostics. Utilizing an AND DLG, both NDs and magnetic beads (MBs) are functionalized with hairpin DNA strands. In the presence of both miRNA-21 and miRNA-155key biomarkers overexpressed in cancerthe hairpin DNAs undergo conformational changes that facilitate DNA-guided self-assembly of NDs and MBs, enriching the target signal. Resonant microwave modulation of ND fluorescence emission allows for high signal-to-noise ratio (SNR) detection by separating the signal from background fluorescence via spin-enhanced analysis. This platform demonstrated ultrasensitive and ultraselective detection of miRNA-21 and miRNA-155 with a limit of detection of 19.8 fM, highlighting its potential as a general biosensing strategy for precision diagnostics involving multiple biomarkers.
