Biomimetic Nano-Hydroxyapatite (nHAp) via Mechanochemical Attritor Milling of Waste Eggshells
Cleared
This concept cleared all seven gates and every voiding sub-test.
| Incumbent displaced | 5% Potassium Nitrate (KNO3) / Sensodyne |
| Measured advantage | VAS pain reduction score at 4 weeks of ~2.0-2.5 for nHAp vs ~5.0 for 5% KNO3 (>2x greater pain reduction in double-blind clinical trials) |
| Time to first revenue | 10 months |
The full analysis goes to the list
Mechanism, operating protocol with real conditions and yields, computed unit economics with a six-scenario stress test, the absence audit, and every resolved citation.
