The dynamics and motion of macromolecular particles suspended in flowing fluids in mesopore systems, and their diffusive collisions and possible adsorption at surface solid boundaries, is a subject of fundamental importance for physical and biological studies. This theme has also promising new applications in the context of mesopore nanotechnology.

The analysis of the macromolecular motion in a flowing fluid inside mesopores is necessary to understand a variety of complex phenomena, as the motion of red blood cells, of suspended nanoparticles in pipe flow, and in polymer processing and composite manufacturing. The analysis is also necessary to describe the adsorption of suspended nano particles inside mesopore systems in a variety of domains. The treatment of polluted air in human lungs, of selective separation of substances and fuel and energy storage, are just some examples of adsorption applications. Adsorption is also an important effect to consider for successful encapsulation and immobilization for biological systems.

A detailed understanding of the influence of fluid hydrodynamics and Brownian movement on the diffusive collisions of macromolecular particles at the solid surface boundaries of mesopores is, however, still absent. Further, the study of the approach dynamics of the macromolecular particles in the neighbourhood of the solid boundaries, and of their diffusive collisions at these boundaries, should permit calculating with precision their adsorption properties, sorption thermodynamics, as well as their overall mobility. This study could also favour a detailed understanding of the phase separation of mixtures of different species of such macromolecules under hydrodynamic flow inside mesopores.
