Fluidic rectification is the process by which fluid flow is allowed to move more easily in one direction than the opposite direction, effectively acting like a one-way valve. This phenomenon is essential in nanofluidic devices, as it can enhance the controlled transport of fluids at the nanoscale, making it particularly valuable for applications in drug discovery and delivery. By utilizing the unique behaviors of fluids at the nanoscale, fluidic rectification contributes to the efficient manipulation and targeted release of drugs within biological systems.
