DOIAbstract
A novel fluorescent paper based immunosensor for the quantification of gliadin content in different food samples was constructed. The device consists of a paper platform modified with amino functionalized mesoporous material. The nanoporous structure and the aminofunctionality increased the anti-gliadin antibodies immobilization capacity of the sensing surface, conferring high sensitivity to the system. The detection limit reached by the described system allowed us to address the control of gluten free foods, which is extremely important to maintain the food safe consumption by patients with celiac disease, wheat allergy measured by immunoglobulin E, non-celiac gluten intolerance and Dermatitis herpetiformis or Duhring disease. The gliadin ...
