What are the Challenges in Nanoscale Fluid Control?
Despite the advancements, several challenges remain in fluid control at the nanoscale:
Viscosity: Fluids at the nanoscale exhibit different viscosity properties, making it challenging to predict and control their behavior. Surface tension: The dominance of surface forces over bulk forces at the nanoscale can complicate fluid manipulation. Fabrication: Creating nanoscale components like nanopumps and nanovalves with high precision is still a technological hurdle. Integration: Seamlessly integrating nanoscale fluid control systems with other nanodevices and macroscale systems is complex and requires further research.
