Celiac.com 10/18/2012 - Currently, there is no convenient way for people with celiac disease to test food for gluten content. In an effort to change that, University researchers in Spain are using Sunrise™ absorbance readers by Tecan, together with Magellan™ V4.0 software to create an accurate, easy to use sensor that can test for gluten in food.

The sensor is an important step toward addressing "increasing demand for rapid, simple and low cost techniques for accurate food analysis in decentralized analytical situations," said Pividori.

The research team measured the performance of the electrochemical immuno-sensor by comparing it with a new magneto-
