Nanomaterial-enabled bioanalytical sensing for doping detection: a critical review of signal transduction, matrix effects, and translation barriers.
Review in Analytical and bioanalytical chemistry, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Doping control requires rapid, field-deployable screening tools to complement laboratory-based confirmatory methods. Nanomaterial-enabled sensors offer portable and easy-to-use platforms by integrating signal amplification, molecular recognition, and small-volume sample analysis. However, despite increasing demonstrations in biological samples, many reported sensors still lack the comprehensive validation required for routine anti-doping practice, including standardized evaluation in diverse authentic samples, matrix-matched calibration, reproducibility assessment, and comparison with established analytical workflows. Therefore, this review evaluates nanomaterial-enabled doping sensors from a matrix-oriented and application-driven perspective. Noble-metal, fluorescent, carbon-based, magnetic, MOF-based, and nanozyme platforms are discussed together with integrated strip-based and wearable formats, covering plasmonic, fluorescence, electrochemical, magnetic, catalytic, SERS, LFIA, and flexible sensing strategies. Particular emphasis is placed on how biological matrices affect target capture, signal generation, quantitative reliability, and field applicability. Key translation barriers are identified, including matrix tolerance, batch-to-batch variability, insufficient standardization, limited authentic-sample validation, and weak integration with anti-doping workflows. By linking material design, sensing format, matrix-specific validation, and practical deployment requirements, this review defines a matrix-oriented framework for assessing the translational potential of nanomaterial-enabled anti-doping sensors.
