An amperometric biosensor for the quantification of food allergens based on an inhibitory immunoassay is presented. As a proof of concept, the experimental conditions were optimized for the detection of β-casein in the 0-10 ppm range. Eight electrochemical cells were integrated into a small-sized portable potentiostat controlled by a smartphone via Bluetooth communication. The determination of β-casein in eight different samples can be measured with the electrochemical biosensor, which has the potential to be modified for the detection of multiple allergens.
