‘Breathalyser’ test to monitor glucose levels

The technology is the result of a partnership between Enfield-based Applied Nanodetectors and the Centre for Process Innovation (CPI), which is part of the High Value Manufacturing Catapult. Using a low cost printed glucose sensor, the breathalyser-style device detects levels of volatile organic compounds (VOCs) in human breath.

“The project evaluated the suitability of a range of gases for monitoring VOCs and benchmarked their performance against existing technology,” said James Johnstone, business manager at CPI.

“We were also able to optimise sensor performance. The incorporation of a low cost, printed glucose sensor offers great potential for the commercialisation of a multi-use and environmentally friendly breathalyser device for daily diabetic management. Regular self monitoring would lead to more effective patient treatment, a reduction in healthcare costs and a shift to more proactive point-of-care treatments.”

The prevalence of diabetes is increasing rapidly around the world, and glucose management is a vital component of treatment. But according to the researchers, the invasive nature of the prick test widely used today to gauge sugar levels means many patients don’t rigorously comply with monitoring. An accurate test that doesn’t require a blood sample could alter how the disease is treated in future.
