Washington: Painful pinpricks for diabetes testing could soon be a thing of past as researchers have created a new type of biosensor that can detect minute concentrations of glucose in saliva, tears and urine.It might be manufactured at low cost because it does not require many processing steps to produce.“It`s an inherently non-invasive way to estimate glucose content in the body,” said Jonathan Claussen, a former Purdue University doctoral student and now a research scientist at the U.S. Naval Research Laboratory.“Because it can detect glucose in the saliva and tears, it`s a platform that might eventually help to eliminate or reduce the frequency of using pinpricks for diabetes testing. We are proving its functionality,” Claussen noted.Claussen and Purdue doctoral student Anurag Kumar led the project, working with Timothy Fisher, a Purdue professor of mechanical engineering; D. Marshall Porterfield, a professor of agricultural and biological engineering; and other researchers at the university`s Birck Nanotechnology Center.“Most sensors typically measure glucose in blood. Many in the literature aren`t able to detect glucose in tears and the saliva. What`s unique is that we can sense in all four different human serums: the saliva, blood, tears and urine. And that hasn`t been shown before,” Claussen said.
