High-Photostability Anti-Counterfeiting Inks via Hydrothermal Carbonization of Biomass into Carbon Quantum Dots
Cleared
This concept cleared all seven gates and every voiding sub-test.
| Incumbent displaced | Fluorescein Dye / Standard Organic Fluorescent Dyes |
| Measured advantage | 12% intensity loss after 2 hours continuous 405nm UV excitation for CQD ink vs 78% intensity loss for Fluorescein Dye (6.5x longer operational lifespan) |
| Time to first revenue | 4 months |
| Gross margin at parity | 97.0% |
| Startup CapEx | $65,000 |
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.
