While nanochannels offer numerous advantages, there are several challenges in their research and application:
Fabrication Precision: Creating uniform and reproducible nanochannels at such small scales is technically challenging. Material Compatibility: Ensuring that the materials used are compatible with the fluids or molecules transported through the nanochannels. Surface Interactions: At the nanoscale, surface chemistry plays a significant role, which can affect the performance of nanochannels. Scalability: Scaling up the fabrication processes from laboratory settings to industrial production remains a significant hurdle.
