Europium-(7-carboxymethoxy-4-methyl coumarin)2 Complex based Electrochemical Probe for DNA based on the Interaction between Them
Bibliographic record
Abstract
The interaction of Eu(III) ion with 7-carboxymethoxy-4-methylcoumarin (CMMC) has been investigated using the potentiometric method in the ethanol-water mixture solvent (0.15 volume fraction). The formation of the different binary, ternary complexes is confirmed by the corresponding pH-potentiometric curves. SUPERQUAD computer program has been used for the refinement of all the calculated constants in our present study. Electroanalytical techniques have been used to confirm the formation of different binary and ternary complexes under investigation. The binding constant of the ternary complex Eu(III)-CMMC-DNA calculated by cyclic voltammetry (CV) and differential pulse (DP) was found to be 1.8 and 2.5x 105 M-1 in Tris-HCl, respectively. The changes in the current intensity have been used for the quantitative determination of DNA over a linear concentration range with LOD of 1.0-1.3 µg/ ml in 0.1 M Tris-HCl buffer.

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.
