Abstract
Targeted drug delivery systems protect healthy tissue in the patient's body while carrying the therapeutic agent to the diseased tissue. For cancer therapy, the enhanced permeability and retention (EPR) effect takes advantage of porosity of the tumor blood vessels and negligible lymphatic drainage. Nanoparticle drug carriers will accumulate in tumors without external intervention. The general problem is how best to release the drug once it has reached the targeted area. Here we show a model micellar drug delivery system that is stable and secure at a normal blood pH of 7.4, but disperses and releases its substrate as the pH drops below 7.0. The micelle is formed from the ionic surfactant, 10-undecenoate, with the hydrophobic tetrabutylammonium counterion. The pH-dependent structure and function differ markedly from other micellar solutions and suggests a key role of the counterion in both stability and solubilization power of the micelle. Our results indicate that tetrabutylammonium counterions can bring about the pH-mediated release of therapeutic agents from micellar drug delivery systems.

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
