Arizona State University (ASU) engineers and clinicians at Mayo Clinic in Arizona have developed a painless self-monitoring blood glucose sensor for patients with diabetes.
Unlike the current glucose monitoring devices which require finger pricks, the new sensor would enable people to determine their glucose levels from the tear fluid.
According to researchers, glucose in tear fluid may give an indication of glucose levels in the blood as accurately as a test using a blood sample.
The project was funded by Mayo Clinic, and BioAccel, an Arizona nonprofit, is providing further funding to conduct experiments to determine how well the new device correlates with use of the current technology that uses blood sampling.
