Fluorescent imaging cytometer for the detection of inflammation biomarkers using temporally multiplexed illumination
Bibliographic record
Abstract
In this study, we present a fluorescence imaging cytometer capable of detecting multiple biomarkers using temporally multiplexed illumination. We independently illuminated the classification and quantitative detection channels using multiwavelength LEDs. To quantify the biomarker concentrations, we employed a sandwich immunoassay with Cy5 dye, while the microbeads were internally dyed with three different intensity levels of quantum dots to distinguish among the three cytokines. We conducted separate tests with three cytokines, namely IFN-α, IL-5, and IL-6, at varying concentrations. The detection ranges for these cytokines were determined to be 10 pg/ml-2500 pg/ml, 30 pg/ml-2500 pg/ml, and 30 pg/ml-2500 pg/ml, respectively. The results of the multiplexed experiment, show that our device can independently detect three different biomarkers in a single assay. This validation demonstrates that our device has potential in diagnosing sepsis and other diseases requiring various laboratory results. With further refinement and development, our device holds great promise for enhancing point-of-care medical services.

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.
