Preparation of Gold/Poly(Thionine) Modified Screen Printed Electrode: Application for Copper(II) Detection in Aqueous Medium, pp. 181-185
Bibliographic record
Abstract
Preparation of an electrochemical sensor based on PTH supported Au nanoparticles for Cu(II) detection in aqueous medium was studied.Screen printed electrodes were used for the cell design enabling detection of Cu 2+ ions in very small solution volume.Onepot synthesis of the Au-PTH nanocomposite on the screen printed electrode surface was performed and square wave anodic stripping voltammetry was used for oxidation of Cu which was preconcentrated through electrochemical reduction.The linear concentration range of the sensor was 2.0 µM -50 µM and limit of detection was calculated as 1.298 μM.Interference of potential metal ions was studied, and no significant interference was observed at the same concentration as Cu(II).Additionally, the reproducibility and the stability of the modified electrode was found excellent.

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.
