ROI Calculation Logic

Implementing this technology for surface coating in public facilities or medical institutions could significantly reduce frequent conventional disinfection tasks. For example, if disinfection work performed by 5 cleaners for 2 hours daily (assuming an annual labor cost of ~$65K (AI est.)) could be reduced by 30% using this technology, an estimated direct cost saving of ~$20K/year (AI est.) is projected. Indirect benefits, such as increased operational rates due to reduced infection risk and enhanced brand value, are also anticipated.

Speed to Market
4× faster than in-house development
This technology's foundational compound has already been synthesized by Shinshu University, and its antiviral and photocatalytic properties are estimated to be established. This allows adopting companies to significantly reduce the time and risk associated with R&D from scratch. With basic material property evaluations complete, rapid progress is expected from application studies to prototyping and evaluation, enabling early market entry.
