Seedless One-Pot Synthesis of Colloidal InAs Quantum Dots Enabling a High-Accuracy Photoplethysmography Oximeter.
Article in Advanced science (Weinheim, Baden-Wurttemberg, Germany), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
Near-infrared (NIR) wavelengths offer a powerful approach for non-invasive physiological monitoring due to the deep tissue penetration and ability to detect various endogenous molecules such as hemoglobin species, water, and lipids. Herein, we demonstrate a high-speed, non-contact photoplethysmography (PPG) system based on indium arsenide (InAs) colloidal quantum dots (CQDs). To this end, a seedless injection-based one-pot method was devised to synthesize monodisperse NIR InAs CQDs. This scalable approach enables precise bandgap tuning from 1.53 to 1.09 eV, aligning with the absorption spectra of hemoglobin and oxyhemoglobin. Furthermore, the proposed CQD-based PPG system is integrated into a real-time acquisition platform. Exercise-induced desaturation tests show that the CQD-based PPG system exhibits consistent oxygen saturation rate (SpO
