Invention Summary

Scientists working at NDSU are developing a low cost diabetes analyzer based on nanostructured K2W7O22.  Research has found that concentrations of acetone in breath is below 0.8 ppm in healthy people but above 1.7ppm for patients with diabetes.  The nanostructure K2W7O22 in the analyzer can detect acetone levels as low as 0.1 ppm at 25oC. 

Diabetes, as one of the most rapidly-growing chronic diseases in the world, results in a number of serious medical complications such as blindness, renal failure, and heart disease, and has become a great threat to human health. [1, 2] Since this disease is caused by metabolic disorders featured with high blood glucose, for patients with diabetes, it is critically important to monitor and keep blood sugar under control, in order to reduce risk of complications. Currently, blood and urine tests are the two most common methods used to diagnosis and monitor diabetes.  Blood tests are the most accurate but are invasive, can be painful, and require specialized equipment.  While urine tests are non-invasive, they are less reliable and inconvenient.  This new invention is a simple, repeatable, reliable and convenient method for both patient and clinical monitoring of a surrogate maker for blood glucose levels.
