An Integrated Microfluidic Dielectrophoretic (DEP) Cell Fractionation System
Bibliographic record
Abstract
In this article we report on a planar miniaturized dielectrophoretic (DEP) microfluidic device developed for the purpose of continuous fractionation and purification of sample suspensions of microscopic particles or biological cells, employing specially shaped nonuniform (isomotive) electric fields. The device integrates three fully functional and distinct sub-units consisting of 1) sheath and sample injection ports, arranged to achieve hydrodynamic focusing of the cell stream; 2) the DEP fractionation region and 3) two sample collection ports. In the DEP fractionation region, the magnitude of the field induced DEP force acting on the particle is essentially constant and independent of the particle’s position and furthermore only dependent on the intrinsic polarization response of the particle, for identical sized particles. The operation and performance in terms of sample throughput, separation efficiency and repeatability of the device was evaluated using test microscopic sized dielectric particles and biological particles, including cancerous cell lines.

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.
