Disposable Capacitive Biosensor for Dopamine Sensing
Bibliographic record
Abstract
Abstract The present paper reports fabrication of a disposable tyrosinase (Tyr) biosensor for rapid detection of dopamine. Tyr immobilized polyaniline/carbon nanotubes/cellulose nanocrystals (Tyr@PANI/CNTs/CNC) conductive film was fabricated on polyvinyl acetate (PVA) transparency and characterized by scanning electron microscopy (SEM) and cyclic voltammetry (CV). Tyr catalyzed dopamine oxidation to o ‐dopaquinone was analysed by CV and capacitance was recorded. PANI/CNTs/CNC film acted as a suitable enzyme support which also showed its synergistic effect in accelerating the biocatalytic oxidation reaction. Tyr biosensor exhibited excellent reproducibility, and specificity towards dopamine with correlation coefficient ( R 2 ) of 0.9508 and limit of detection (LOD) of 1.57 nM within linear concentration range of 7–1000 mM. The study suggested practical utilization of disposable biosensor towards dopamine detection in biological fluids.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
