A membrane-free system for continuous glucose monitoring

Summary

Current internal sensors used for continuous glucose monitoring in diabetic patients rely on physical barriers to isolate the glucose, making them less responsive and adaptive. This technology is a membrane-free, graphene-based system that responds to glucose in a concentration-dependent manner and enables rapidly responsive, reliable, and continuous measurement of blood glucose levels. Development of this technology could help create the next generation of blood glucose monitors that are simple, fast, sensitive, and help diabetic patients monitor their blood glucose more easily and accurately.

Technology Benefits

Does not require a membrane or other semi-permeable barrier for accurate measurementsAllows for continuous, real-time monitoring of glucose levelsImproved sensitivity over a wide range of glucose concentrations Simplified fabrication of deviceCan be used to develop less invasive glucose sensing devices Patent Information:Patent Pending (WO/2015/192064)Patent Pending (WO/2016/205190)Tech Ventures Reference: IR CU15153, IR CU14370, IR CU13180
