A Novel PCB77 Electrochemical Sensor Based on Nano-functionalized Electrode and Selected Aptamer
Bibliographic record
Abstract
is a highly toxic substance that endanger ecological environment and human health. In our study, a novel PCB77 electrochemical sensor based on nano-functionalized electrode and selected aptamer was designed. -cyclodextrin-Au nanoparticles (-CD-AuNPs)/Nafion modified glassy carbon electrode (GCE) was used for amplify signal that enable sensitivity advanced, and the selected electroactive ferrocene (Fc) labed aptamer was assembled on the electrode surface via the host-guest recognition between -CD and Fc. The detection was carried out according to the signal changed caused by transformation in the configuration of aptamer before and after the existence of PCB77. By this strategy, a detection limit down to 1.610-8 g/L was achieved. Moreover, it exhibited reliable selectivity against co-existing chemicals.

How this classification was reachedexpand
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.
