Abstract
The present invention provides systems, devices, signaling polynucleotides (SPNs), detection agents and methods for detecting the presence and/or absence of one or more allergens in a sample particularly a food sample. The detection system includes a separate sampler, at least one disposable detection vessel for receiving and processing a test sample and a detection device for measuring a fluorescent signal. SPNs derived from aptamer that bind allergens are provided as detection agents. SPNs have a single open structure, and are labeled with a fluorophore. Changes in fluorescence polarization of SPNs upon the binding of allergens are measured to calculate the allergen content in a sample.
