Cationic Polythiophene for Label-Free, Colorimetric and Fluorometric Detection of DNA
Bibliographic record
Abstract
In order to respond to new demands and needs in modern medical diagnostics and biomedical research applications, a lot of new DNA detection systems have been reported [1-7]. However, most of these methods have the disadvantage of requiring the chemical coupling of a photoactive or electroactive tagging agent onto the target or the probe prior to detection. Some oligonucleotidefunctionalized conjugated polymers have enabled the transduction of hybridization events, without labeling of the DNA target [8-10]. Here we describe the use of a watersoluble, cationic polythiophene that can specifically transduce the binding of an appropriate oligonucleotide to its target into a clear optical (colorimetric or fluorometric) signal. This simple, rapid, sensitive and selective methodology does not require any chemical modification on the probes or targets.

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.
