ABSTRACT

The diffusion of chemical substances in a suspension of micron-scale biological cells is an important phenomenon. For example, the mass transport of various substances such as oxygen, CO2, and low-density lipoprotein in the bloodstream is often discussed in the field of medical engineering because of the physiological and pathological importance of these processes. These substances are dispersed not only by Brownian diffusion but also by the micron-scale flow field generated by blood cells. The diffusivity of platelets increases markedly compared to Brownian diffusivity because of the micron-scale flow field [1].
