Osmosis plays an essential role in a wide range of phenomena, and therefore it is useful to understand how to manipulate the rate at which osmosis occurs. In the present study we conduct molecular dynamics simulations to consider the influence of solute size on the osmotic pressure gradient which drives the flow. Our results show how selective choice of the size of the solute can enhance, or hinder, the establishment of a strong osmotic gradient.
