Single Molecule DNA Resensing Using a Two‐Pore Device
Bibliographic record
Abstract
A nanofluidic device is presented that, enables independent sensing and resensing of a single DNA molecule translocating through two nanopores with sub-micrometer spacing. The device concept is based upon integrating a thin nitride membrane with microchannels etched in borosilicate glass. Pores, coupled to each microchannel, are connected via a fluid-filled half-space on the device backside, enabling translocation of molecules across each pore in sequence. Critically, this approach allows for independent application of control voltage and measurement of trans-pore ionic current at each of the two pores, leading to 1) controlled assessment of molecular time of flight, 2) voltage-tuned selective molecule recapture, and 3) ability to acquire two correlated translocation signatures for each molecule analyzed. Finally, the rare cocapture of a single chain threading simultaneously through each of the two pores is reported.

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.
