“…In this perspective, reliable, accurate, and highly sensitive and selective methods are needed to evaluate, with assurance, if a certain allergen is (or not) present in a foodstuff. The methodologies available for allergens detection can be divided into three main groups: immunoassays for protein detection (Besler et al, 2002;Monaci and Visconti, 2010;Taylor et al, 2009), DNA-based methods (Słowianek and Majak, 2011;Monaci and Visconti, 2010) and mass spectrometry (Monaci and Visconti, 2009). Biosensors have been emerging recently as powerful alternatives to classical methods for the detection and quantification of allergens, but their application in this field is still scarce.…”
