We investigated the gradient diffusion of red blood cells (RBCs) in blood flow in a microchannel. The effects of flow rates, and hematocrit (Hct) on the gradient diffusion were investigated experimentally. Under the same hematocrit condition, the gradient dispersion coefficient was increased almost linearly to the flow rate. The gradient diffusion dominated over Brownian diffusion in most of high hematocrit conditions. These findings provide useful information in understanding mass transport in small vessels.
