Thermomechanical responses of microfluidic cantilever capture DNA melting and properties of DNA premelting states using picoliters of DNA solution
Bibliographic record
Abstract
Melting or thermal denaturation of a DNA molecule and the different bubble-rich, premelting DNA states that serve as a precursor for DNA thermal denaturation are vital events in DNA thermophysics. In this study, we employ cantilever-based sensing to firstly pinpoint the occurrence of DNA melting and identify the temperature Tm characterizing the melting. Very importantly, this sensing is carried out with an extremely small volume (∼picoliters) of DNA sample with the cantilever demonstrating an extremely high sensitivity on the order of mJ/g⋅K corresponding to pico-Joules of energy input. Secondly, this same large sensitivity of the cantilever is used to quantify the hitherto unknown thermophysical properties of the bubble-rich DNA premelting states. In fact, for both the melting and premelting states, the cantilever provides a framework to calculate the specific heat capacity and the storage and loss moduli of the cantilever-DNA-solution system, thereby establishing a platform for quantifying DNAs' thermo-mechanical behavior.

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.
