Portable 3D-printed electrochemiluminescence sensor for simultaneous glucose and lactate monitoring.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Fast and reliable monitoring of metabolic biomarkers, including glucose and lactate, is critical for chronic diseases, sepsis, and other scenarios involving physiological stress. However, most diagnostic options depend on multiple serial tests, require complicated testing apparatus, and are too expensive to be useful in the point-of-care arena. To address these limitations, we present a portable, low-cost, and 3D-printed (3DP) electrochemiluminescence (ECL) biosensor capable of simultaneously detecting glucose and lactate in a single step. The biosensor incorporates interdigitated electrodes (IDEs) within a bipolar electrode (BPE) electrochemical system to enhance electron transfer and signal amplification. Through careful optimization of voltage, luminol concentration, and pH, strong and reproducible ECL signals were achieved, with detection limits of 0.1 mM for glucose (linear range 0.1 mM to 5.0 mM) and 80 µM for lactate (linear range 0.1 mM to 4.0 mM). Real serum analysis yielded 95-102% recovery rates, validating the device's clinical relevance. Combining an inexpensive smartphone-based readout and fabricated with low-cost carbon and polylactic acid (PLA) filaments, this device offers a scalable and field-deployable approach to real-time, decentralized diagnostics. The proposed prototype fills a critical void between laboratory analysis and standard healthcare needs and promotes accessible and affordable metabolic monitoring for underserved populations.
