Abstract
A continuous online technique based on electric cell-substrate impedance sensing (ECIS) was demonstrated for measuring the concentration and time response function of fibroblastic V79 cells exposed to nanomaterials such as quantum dots (QDs) and fluorescent gold nanoparticles. The half-inhibition concentration, (ECIS50), the required concentration to attain 50% inhibition of the cytotoxic response, was estimated from the response function to ascertain cytotoxicity during the course of measurement. The ECIS50 values agreed well with the results obtained using the standard neutral red assay. Cadmium selenide quantum dots showed direct cytotoxicity with the ECIS assay. For the cadmium telluride quantum dots, significant toxicity could be assigned to free cadmium, although additional toxicity could be attributed to the QDs per se. The QDs synthesized with indium gallium phosphide and the fluorescent gold nanoparticles were not cytotoxic.

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
