Nanotechnology takes on diabetes

The Next Generation

A sensor which can be used to screen for diabetes in resource-poor settings has been developed by researchers and tested in diabetic patients, and will soon be field tested in sub-Saharan Africa.

A low-cost, reusable sensor which uses nanotechnology to screen for and monitor diabetes and other conditions, has been developed by an interdisciplinary team of researchers from the University of Cambridge, for use both in clinics and home settings.

The sensors use nanotechnology to monitor levels of glucose, lactate and fructose in individuals with diabetes or urinary tract infections, and change colour when levels reach a certain concentration. They can be used to test compounds in samples such as urine, blood, saliva or tear fluid.
Earlier this year, clinical trials of the sensors were carried out at Addenbrooke’s Hospital to monitor glucose levels in 33 diabetic patients. Recently, the team has also partnered with a non-governmental organisation to deploy…
