Electrokinetically-Induced Flow Over a Nano-Hole Array Sensor
Bibliographic record
Abstract
A microfluidic device with an embedded surface-plasmon resonance (SPR) sensor was developed. The detector allows real-time monitoring of chemical processes on-chip. Microfabrication of a poly(dimethylsiloxane) chip incorporating a gold-on-glass nano-hole array (SPR sensor) was developed. This was the first time a SPR sensor operating in transmission mode was built in an on-chip format. Electrokinetic transport phenomena in a microchannel over the gold-on-glass plate was modeled using Computational Fluid Dynamics. The modeling results indicated that the flow over the gold-on-glass plate was pressure driven since there was no variation in electrical potential over the conductor (gold). The flow was electrokinetically driven where an electric field was present. The exchange of solutions in the nano-holes was also modeled and it was found that this process took less than a second. This permeation time is expected to scale with the diffusion coefficient. Lastly, preliminary optical measurements were performed to demonstrate the efficiency of the array of nano-holes as on-chip SPR sensors.

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.
