Nano fluidic systems function by utilizing the principles of fluid dynamics at the nanoscale. At this scale, the behavior of fluids can be quite different from what we observe at the macro scale. For example, capillary action and electroosmotic flow become significantly more pronounced, allowing for highly efficient fluid transport. Materials used to construct nano fluidic devices often include silicon, glass, and various polymers. These materials can be precisely engineered to create channels and structures that are only a few nanometers wide.
