Cornell NutriPhone

The Cornell NutriPhone has resulted through a collaboration between scientists and engineers in Nutritional Sciences and Mechanical and Aerospace Engineering at Cornell University. When we began this partnership, our initial targets were to develop diagnostic tools that were affordable and accessible for populations in both resource-limited and resource-rich settings. From a technical standpoint, we also decided to focus on adapting conventional laboratory assays and gold standard methods rather than focusing on proxy biomarkers that are widely used in most field-based rapid diagnostic tests. We now have several issued patents for our technology and prototypes for low-cost accurate quantitative determination of several micronutrients including vitamins D and B12 concentrations from a drop of blood at the point-of-care. 

In recent work, we have started examining other matrices such as saliva as well as food to measure micronutrient status. We received a $100K prize in 2020 from the National Institutes of Health for our concept of non-invasive rapid diagnostics for assessment of iron status and inflammation from a drop of saliva.
