ROI Calculation Logic

For a facility conducting 100,000 tests annually, assuming a 50% reduction in test time per case and a 20% reduction in associated personnel and reagent costs, the annual cost reduction is estimated at ~$350K (AI est.), calculated as: (100,000 cases × $35/case (AI est.) × 0.20) + (100,000 cases × $17/case (AI est.) × 0.50).

Speed to Market
6× faster than in-house development
This technology's core principles for high-sensitivity pathogen detection are well-established. Key elemental technologies, such as droplet formation and optical detection, are widely applicable to existing microfluidic devices and analytical instruments. This significantly reduces the need for greenfield R&D, compressing the lead time from proof-of-concept to product commercialization. Early market entry is achievable by focusing on integration as a module into existing testing systems and optimizing software.
