ROI Calculation Logic

Applying this technology to Drug Delivery Systems (DDS) could optimize drug costs through precise release control, maximizing efficacy and minimizing waste. For a pharmaceutical company using ~$6.5M (AI est.) in drugs annually, a 30% reduction in drug waste could yield ~$2.0M (AI est.) in annual cost optimization. This is calculated as direct drug cost savings, separate from enhanced treatment outcomes or reduced side effects.

Speed to Market
6× faster than in-house development
The fundamental principles of Metal-Organic Framework (MOF) synthesis, polymer gel composite formation, and chemical species release via external force have been established through university-level basic research. This allows licensees to significantly reduce initial R&D, potentially commencing application development within ~6 months. Leveraging existing MOF synthesis and gel manufacturing processes could enable rapid market entry.
