International health insurance policies may soon contain an innovative diagnostic test for diabetes, following the development of a groundbreaking biosensor.
Research conducted at the Birck Nanotechnology Center and funded by the National Science Foundation and the US Office of Naval Research provided good evidence of the functionality of the device, which can detect elevated levels of glucose in tears and saliva.
Findings from the study were published in the journal Advanced Functional Materials and it is hoped the development may eventually eliminate the need for pinprick blood sugar level testing.
"It's an inherently non-invasive way to estimate glucose content in the body," research scientist at the U.S. Naval Research Laboratory and former Purdue University doctoral student Jonathan Claussen said.
He pointed out that this innovation is the first proof that glucose can be sensed in saliva, tears, urine and blood, or "all four different human serums".
The healthcare specialist stated that the biosensor is portable, fast and versatile, with the potential to be adapted to monitor alcohol levels in the blood or diagnose Alzheimer's and Parkinson's.
