Speed to Market
5× faster than in-house development
Developing equivalent high-performance fullerene nanotubes and applying them to sensors in-house would require extensive R&D across materials science, nanotechnology, and sensor engineering, typically taking over 4 years. This technology has established hydrophilization and nitrogen-doping mechanisms for functionality, and its manufacturing process is simplified. This allows licensees to focus on integration into existing sensor platforms, potentially shortening time-to-market to approximately 10 months and enabling faster revenue generation and market entry.
