Non-invasive Optical sensor for the monitoring of Blood Glucose in diabetes

Project Details

Principal Investigator:  Prof P A Kyriacou

Co-Investigators:  Professor A Petros (Great Ormond Street Hospital for Children)

Researcher:  Dr V Rybynok

Funding:  Emerald Fund, City University London, Great Ormond Street Hospital for Children

Project Description

Currently, blood glucose can only be monitored through the use of invasive techniques which involve drawing blood through a small pinprick. The market is very large as all diabetics in the world are potential users of the sensor. The number of diabetics in the UK has increased since 1996 from 1.4 to 1.8 million people. Worldwide it is expected to grow from 150 million in 2004 to 220 million by 2010 and 300 million by 2025. We are proposing to develop an easy to use non-invasive and calibration free finger optical sensor for the accurate and continuous measurement of blood glucose. This will be accomplished by using a novel patented technology we have developed previously, named Dynamic Pulsatile Spectroscopy (DPS). If a completely non-invasive method to determine blood glucose concentrations could be established this would have significant implication for the diabetic community on the management of diabetes.
