Abstract
Abstract Broadly, the industrial applications of hydrazine cause environmental pollution and damage to living organisms because of the high toxicity of hydrazine. Therefore, monitoring hydrazine in the environmental system is of great significance to human health. Here, a new fluorescent probe PC‐N 2 H 4 based on corrole dye was developed for the detection of hydrazine that had excellent specificity, low limit of detection (LOD: 88 nM), and a wide pH range (6–12). Upon addition of hydrazine into the probe solution, the strong red fluorescence was ‘turned on’ centred at 653 nm with a 127‐fold fluorescence intensity enhancement. The detection mechanism was proved using ESI‐MS, 1 H NMR, and density functional theoretical calculations. Importantly, the probe was utilized to fabricate a ready‐to‐use test strip to realize the visual inspection of hydrazine. Furthermore, PC‐N 2 H 4 was successfully applied for practical detection of hydrazine in water samples with satisfactory recoveries ranging from 96.2% to 105.0%, and indicating that the designed PC‐N 2 H 4 is highly promising for hydrazine detection in an aqueous environment. Considering the diverse toxicological functions of hydrazine, PC‐N 2 H 4 was also successfully used to image exogenous hydrazine in HeLa cells and zebrafish.

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
