This device is aimed at ensuring that the sample is uniformly and equivalently reacted with the antibody on the NC membrane in each test when the microfluidic liquid system is introduced to the chip. In this study, the developed microfluidic chip can avoid the presence of the sample and conjugate pads in the chip, while the precision of the chromatography system can be greatly improved using the same particles, NC membrane and antibody alongside the traditional strip. The results, taking the detection of cTnI as an example, revealed that the coefficient of variation (CV) is controlled within 4%, while the maximum record of the contrast chromatographic reagent strip can reach 15%. Additionally, the detection sensitivity can maintain the same order of magnitudes with that of the traditional chromatographic strip. With the results, the determination correlation of the developed microfluidic chip has been greatly improved. In addition, the CV of the chip in this study is greatly improved in comparison with that of the traditional strip. The biggest improvement lies in the mixing between the sample and the microspheres, indicating that this is a new approach to improve the CV of the traditional strip.
