Recent applications of microfluidic immunosensors

The fast diagnosis of diseases is vital in the early stages of the cure of illnesses. Although conventional procedures have been broadly employed in clinics, newly presented microfluidic microchips are becoming more attractive. The benefits of the new microfluidic system involve more fast diagnosis, the need for low patient samples and reagents, user-friendly application, and high repeatability in the quantification of biomolecules. The primary aim of this review is to offer a summary of the effect of the applied nanomaterials in the fabrication of novel immunosensor-based microfluidic sticks and to carefully explore different applications of microfluidic systems in the determination of bioagents. New kinds of immunosensor-based microfluidic systems for coronavirus disease and HIV are also explored. The next types of biomedical diagnosis will mainly rely on point-of-care (POC) methods, which propose rapid and sensitive detections. However, microfluidic systems propose a high potential to fabricate reliable POC devices.
