2026-05-11T07:56:05Z mediaingredientmech-agentic-curation LLM REVIEWED_METAL_NTA_COMPLEX UNMAPPED Classified as a single metal-NTA complex and left unmapped because no exact local ontology term for copper-NTA was verified; generic NTA or copper mappings would not preserve complex identity.
2026-08-06T00:00:00+00:00 edison_literature_identity LLM ANNOTATED Edison LITERATURE (PaperQA3) identity research; report at research/ingredients/Copper-NTA-edison-literature.md (local artifact — research/ is gitignored, so the findings are quoted here rather than linked). Report verdict: **Recommended interpretation:** “Copper-NTA” denotes a **copper(II)–nitrilotriacetate coordination complex**, normally abbreviated **Cu-NTA** or **Cu(II)-NTA**, rather than elemental copper, free copper ion, nitrilotriacetic acid, or nitrilotriacetate alone. A directly examined cell-culture paper used an equimolar **1:1 Cu:NTA complex**, administered at 1–10 μM Cu(II) in maintenance culture medium No ontology CURIE was proposed. Recorded as provenance only — no grounding applied from this run. Edison's recommendations are deliberately conservative, and a plausible identifier promoted by a mechanism that never decided anything is what #203 and #263 exist to undo. Any CURIE above is a curator's to accept or reject.
