Abstract
A general-applicable two-phase ligand exchange method is developed to prepare a series of monodisperse water-soluble AuAg nanoclusters. This method relies on the ligand exchange of the water-soluble ligands (e.g., tiopronin, captopril, N-acetyl-l-cysteine, 4-mercaptobenzoic acid, glutathione, and mercaptosuccinic acid) with phenylacetylene and triphenylphosphine co-protected AuAg precursors. Both polyacrylamide gel electrophoresis (PAGE) and transmission electron microscopy (TEM) indicate the monodispersity and ultrasmall size of the prepared water-soluble metal nanoclusters. In addition, the structure has also been characterized by UV–vis absorption spectroscopy, extended X-ray absorption fine structure (EXAFS), electrospray ionization time-of-flight mass spectra (ESI-TOF-MS), etc. The preliminary application of the as-prepared AuAg nanoclusters protected with tiopronin has been explored via the postmodification of the carboxyl groups of thiols with doxorubicin (DOX).

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
