Sweet tear sensor could ease pain of diabetes

摘要

People with diabetes may soon benefit from pain-free glucose monitoring, thanks to a sensor that measures the sugar in tears. Current techniques for glucose self-monitoring involve drawing blood onto test strips and analysing the samples with a separate device. This painful, multi-step approach deters some patients from testing their glucose levels as often as is recommended. A team from Arizona State University in the US believes that its non-invasive method would encourage diabetes patients to test their glucose levels regularly.
