Horseradish Peroxidase Nanopatterned Electrodes by Click Chemistry: Application to the Electrochemical Detection of Paracetamol
Bibliographic record
Abstract
Abstract We propose the fabrication of nanostructured glassy carbon (GC) electrodes modified with horseradish peroxidase (HRP) for the detection of paracetamol. This was accomplished by inducing the nanostructuration of GC via the adsorption of polystyrene nanospheres (900 nm diameter) followed by electropolymerization of N‐(10‐azidodecyl)pyrrole. The nanospheres were then removed and nanostructured polypyrrole‐GC was submitted to click reaction in presence of ethynyl‐biotin that was further coupled to HRP‐avidin. The electrode was then used to sense the electrochemical reduction of the enzymatically generated electroactive oxidized species of acetaminophen (NAPQI) in the presence of hydrogen peroxide. The nanostructured electrode with HRP exhibits a fast response towards NAPQI reduction and improved performances in terms of sensitivity and limit of detection compared to non structured electrode.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
