New patch points to bloodless diabetes monitoring

Researchers at the University of Bath have utilised graphene to create an adhesive patch which could be used to measure glucose levels of people with diabetes without having to take a painful finger-prick test.

The patch created by the team, who were supported by the Engineering and Physical Sciences Research Council (EPSRC), Medical Research Council (MRC) and the Sir Halley Stewart Trust, draws glucose out from fluid between cells across hair follicles.

The follicles are individually accessed through an array of miniature sensors using a small electric current. Glucose is collected in tiny reservoirs and can then be measured.

The design allows readings to be taken every ten to 15 minutes over the course of several hours, and also does not require calibration with a blood sample, removing the requirement for a finger prick blood test.

The collaborative study between researchers at Bath's Physics, Pharmacy and Pharmacology and Chemistry Departments, which has been published in Nature Nanotechnology, has been widely reported in the media, with articles appearing in the Daily Mail, Daily Express and local press.
