The detection sensitivity of immunostick colorimetric assay has been increased by using a bio-nanocapsule as a scaffold for oriented immobilization of immunoglobulin Gs. This immunostick produced ∼82-folds stronger coloration in the detection of food allergens and reduced detection time by a factor of 5.
Keywords: bio-nanocapsule; food allergens; food safety analysis; immunostick; oriented immobilization.
