ABSTRACT
The traditional-immunological strategies for clinical laboratories often rely on large and expensive instruments and skilled operators, and the measurement time is also long. However, the sensitivity of these strategies is still unsatisfactory. It is urgent to research and develop the point-of-care testing (POCT) featured as a highly sensitive, accurate, and rapid/POCT diagnosis. The Microfluidic chips have multi-advantages that are suitable for the clinical POCT diagnosis: high sensitivity, throughput, and automation. Recently, the Microfluidic-immune chips developed based on the microfluidic technology combined with immune detection have considered not only hotspots in the related research but also benefit to the tumor marker detection, antigen and antibody detection of infectious diseases, autoantibody detection, hormone detection, and other fields. However, there are still many challenges to be overcome during the application of chips, such as more effective microfluidic manipulation, more sensitive collection, and analysis of reaction signals.
