A breathalyser that can monitor blood glucose levels, which has the ability to replace finger pricking for people with diabetes, is being developed.
The breathalyser will be a collaboration between Applied Nanodetectors Ltd, a Middlesex-based technology company, and the Centre for Process Innovation (CPI) based in Teesside.
Work has begun into designing and printing of this novel glucose sensor, which can come in the form of a breathalyser. The sensor allows the measurement of volatile organic compounds (VOC’s) - chemicals that have a higher vapour pressure at ordinary room temperature - in human breath.
In a study done in 2014,C Walton et al reported: "It has been noted that breath in people suffering with diabetes has a different odour and thus it may be possible to use breath analysis to monitor the blood glucose concentration.”
Glucose testing is vital for people with type 1 diabetes, as well as people with type 2 diabetes who are at risk of hypoglycemia.Most people have to have their finger pricked so that they can have their blood sugar levels checked, this can be painful and unpleasant, especially for younger patients.
At the moment there are no other devices that offer non-invasive handheld breath testing that have met a price point suitable for the mass market, but the development of this device could change that.
Dr Victor Higgs, Managing Director at Applied Nanodetectors Ltd, added: "This would provide diabetics with a non-invasive easy to use test compared to the established finger prick method. This new sensor platform offers both high sensitivity and industry leading reliability and can be modified for use in new clinical applications.”
Futhermore, being able to print glucose sensors allows us to mass produce the product for an extremely low cost per unit."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," said James Johnstone, Business Manager at CPI.
Further development will look to upscale the sensor and integration into a point-of-care diagnostic device. Higgs added that "this will enable more efficient healthcare delivery leading to improved patient outcomes.”
At the moment, there has been no official date on when we can expect the device to come to the market.
