An Aptamer-Amphiphile to Detect a Major Cow Milk Allergen
The Kokkoli group has designed an aptamer-amphiphile and used it to decorate the surface of a liquid crystal. The biosensor detected beta-lactoglobulin, a major allergen from cow’s milk, at 0.18 ppm, thus demonstrating that it has the potential to be used for the fast and label-free detection of beta-lactoglobulin in food processing facilities. This work was in collaboration with the Labuza group in the Department of Food Science and Nutrition at the University of Minnesota.
