IGHE and allergic disease: Many conventional commercial allergy measurement techniques are available to analyze IgE concentration, e.g., enzyme-linked immunosorbent assay (ELISA) [9], surface plasmon resonance (SPR) [10], quartz crystal microbalance (QCM) [11] sensing techniques, chemiluminescence immunoassay (CLIA) [12], and Abbott AxSYM fluorescence polarization immunoassay (FPIA) [13], etc. Unfortunately, all the commercial allergy measurement instruments mentioned above require multifarious testing protocols, long operation time for sampling analysis procedures, expensive analytical instruments, and many analysts.
