Dynamics of BSA adsorption onto a photoablated polymer surface in a dielectric microchip
Bibliographic record
Abstract
Dielectric impedance spectroscopy in a microchip was used for monitoring the adsorption of biomolecules onto a heterogeneous polymer surface obtained after the photoablation process. The sensor comprises a thin dielectric layer with two parallel carbon microband electrodes on the one side, and the photoablated surface on the other. The biomolecules need not to be labelled, as in an optical biosensor, even if they need to be attached to the polymer surface coupled with the microelectrodes when a biomolecular interaction occurs. Based on this principle, a flow sensor has been developed to record the adsorption dynamics illustrated with BSA coating on the heterogeneous surface in a linear dynamic range from 1 picomolar to 1 nanomolar at a fixed low frequency. Modeling the dielectric interface using an appropriate equivalent circuit permits extraction of the values of the interfacial impedance for ultralow protein concentrations. The promising results obtained with this methodology make it a competing method in comparison with optical or electrochemical transduction for biosensor development.

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.
