Abstract
Provided is an allergen detecting apparatus that combines with an allergen microarray chip, the apparatus comprises a microfluidic chip and a clamping unit. The allergen microarray chip can be any commercial chip and a reaction region of the microfluidic chip is configured to fit tightly with a microarray region of the allergen microarray chip allowing a sample or a reagent to contact with an allergen protein disposed on the microarray region. The present invention also provides a platform comprising a control system which configured to automatically perform the mixing and binding reactions of the antibody and antigen in the apparatus of the present invention to achieve a faster, more cost-effective, and accurate detection of allergen.
