estimated ROI · USD · AI analysis
ROI Calculation Logic

For 1,000 sepsis patients, reducing average diagnosis time by 2 days (from 7 to 5 days). Assuming a hospital stay cost of ~$500/day (AI est.), the annual reduction effect is calculated as 1,000 patients × 2 days × ~$500/day = ~$1M (AI est.). Additionally, avoiding severe complications through early appropriate treatment is expected.

Speed to Market
4× faster than in-house development
This technology, developed by the National Institute for Materials Science (NIMS), likely has advanced foundational technical validation and prototype development. The algorithm for measuring the unique electrochemical potential of membrane vesicles is established, and biosensor technology can leverage general-purpose techniques. This allows for significant time reduction compared to developing from scratch. Focusing on integration into existing medical devices or productization as a Point-of-Care Testing (POCT) device could enable rapid market entry.
