摘要
Numerical modeling has been used to investigate the disparity in performance and sensitivity that has been reported for flow displacement immunosensors based on bead-packed columns, membranes, and capillary tubes. The simulations strongly suggest that the high surface areas in the porous media systems may actually be detrimental to sensor performance because of large numbers of free antibody binding sites. Since the free antibody sites are created during the wash step in which the baseline is established, wash protocols are critical in optimizing the sensitivity for a given displacement sensor.
