Abstract
Abstract In some industrial districts, abuse discharge of waste water has resulted in serious Hg 2+ pollution in seafood, grain, and even drinking water. In order to protect people from mercury(II)‐polluted food and water, many solid‐state fluorescent Hg 2+ ‐sensing materials are developed in terms of facile operation. However, one primary challenging issue is the restricted sensitivity caused by hindered slow diffusion of aqueous testing samples inside these conventional hydrophobic, dense, and rigid film materials. Herein, robust hydrophilic fluorescent hydrogel‐coated flexible paper/textile film chemosensors are reported. Their design relies on a specific chemical reaction between Hg 2+ and the grafted thiourea moieties to induce remarkable “green‐to‐blue” emission color change. Thanks to their hierarchical porous structures fixed by interwoven paper/textile fibers, these flexible chemosensors allow fast capillary‐force‐driven mercury(II) diffusion into the hydrophilic hydrogel matrix, thus enabling visual detection of nearly nM‐level Hg 2+ . On this basis, robust fluorescent hydrogel‐coated wearable sensing gloves are fabricated for the first time, which significantly facilitate infield visual detection and effectively protect operators far from the toxic Hg 2+ ‐polluted samples. These developed flexible wearable sensing systems might not only hold great potential applications in mercury(II) detection, but also inspire the development of next‐generation sensing apparatus for other food and environmental pollutants.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
