Immunosensing microfluidic devices are reviewed. Devices are commonly fabricated in glass, silicon, and polymers, with polymers seeing greater attention in recent years. Methods have been developed to immobilize antibodies and other molecules and resist non-specific adsorption through surface modification. The most common detection method is fluorescence, followed by electrochemistry. Various microfluidic designs have been reported for immunoassay applications. The observed trends in microfluidic immunoassay applications closely resemble the trends of general immunoassays, where large molecules are detected principally through a sandwich procedure, while competitive assays are used to detect smaller molecules. The following future trends are suggested: more sensitive detection, increased integration and miniaturization, multianalyte analysis, more robust reagents and devices, and increased functionality of surface treatments.
