A New Approach to Glucose Monitoring Using a Non-Invasive Ocular Amperometric Electro-Chemical Glucose Sensor for the Diabetics

A non-invasive method of monitoring blood glucose would present major advantages over existing methods, since the problems listed in this study are specific to invasive testing procedures. Our group will attempt to develop a new technology for the noninvasive monitoring of tear glucose levels, potentially blood glucose monitoring, using a disposable contact lens embedded with glucose sensing metal that is fast and simple, and is more economical than existing methods. Our precision tear glucose sensing system is based on measuring the tiny electric current, probably nanoor pico-ampere scale, in order to monitor the tear glucose concentration by using an electrochemical detection technique. The proposed study with a glucose sensing contact lens with implanting the metallic sensor on top of lens is capable of monitoring glucose accurately enough to satisfy medical use criteria. The cost to patients of such a method would be significantly less over time than existing methods because only a monitor with contact lens would be required, and the high monthly expense of testing strips would be avoided. In addition, patient acceptance would be very high because of the non-invasive nature and the simple and safe use of the procedure.
