Abstract
AIM: Toxicity of nanoparticles developed for biomedical applications is extensively debated as no uniform guidelines are available for studying nanomaterial safety, resulting in conflicting data obtained from different cell types. This study demonstrates the varied toxicity of a selected type of nanoparticle, cadmium telluride quantum dots (QDs), in three increasingly complex cell models of the peripheral nervous system. MATERIALS & METHODS: QD-induced cytotoxicity was assessed via cell viability assays and biomarkers of subcellular damage in PC12 cells and mixed primary dispersed dorsal root ganglia (DRG) cultures. Morphological analysis of neurite outgrowth was used to determine the viability of axotomized DRG explant cultures. RESULTS & DISCUSSION: Cadmium telluride QDs and their core metals exert different degrees of toxicity in the three cell models, the primary dispersed DRGs being the most susceptible. alpha-lipoic acid is an effective, multimodal, cytoprotective agent that can act as an antioxidant, metal chelator and QD-surface modifier in these cell systems. CONCLUSION: Complex multicellular model systems, along with homogenous cell models, should be utilized in standard screening and monitoring procedures for evaluating nanomaterial safety.

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
