In the case of nanopores, these microscopic channels provide a path for the controlled flow of fluid, allowing scientists to manipulate and harness it for a wide range of purposes.
Hydrodynamic flow occurs when a fluid, such as water or air, moves in response to an applied force. This force can be generated by pressure differentials, gravity, or other external factors. In the context of nanopores, the principle of hydrodynamic flow refers to the flow of fluid through these nanometer-sized channels.
Nanopores act as conduits for the fluid, providing a pathway for its movement. The size and shape of the nanopores, as well as the properties of the fluid itself, determine the behavior of the hydrodynamic flow. By carefully designing and engineering nanopores, scientists can control the flow patterns and achieve specific outcomes.
Nanopores play a pivotal role in facilitating the hydrodynamic flow necessary for the function of the DNA-powered electromotor. These nanometer-sized channels act as conduits for the fluid, allowing controlled flow and enabling the generation of mechanical motion.
