Abstract
This work explores a fabrication technique for producing glass-based microfluidic devices for the purpose of performing capillary electrophoresis analysis of biochemical samples, including the detection of fluoroquinolone-class antibiotics in cow’s milk. This exploration employs ultraviolet laser ablation to produce high-quality microcapillaries in two low-cost glass substrates: soda-lime glass and borosilicate glass. This technique enables the in-house fabrication of such devices without the need for caustic chemical etchants and yields smooth channel surfaces capable of inducing electroosmotic flow. This study provides a thorough characterization of the laser milling system, demonstrating the relationship between optical fluence and microchannel cut depth and quality. Furthermore, a practical application of the microfluidic device is demonstrated experimentally via an electrophoretic separation of a cow’s milk sample containing the antibiotic levofloxacin. This experiment showed a detection time of less than 5 minutes. [2025-0131]

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 it
