Nanofluidics is an interdisciplinary field of study that bridges hydrodynamics, statistical physics, chemistry, materials science, biology, and other fields to investigate the transport of fluids and ions on the nanometric scale. The progress in this field, however, has been constrained by challenges in fabricating nanofluidic devices suitable for systematic investigations. Recent advances in two-dimensional (2D) materials have revolutionized the development of nanofluids.

Confining DNA in nanochannels is an important approach to studying its structure and transportation dynamics. Graphene nanochannels are particularly attractive for studying DNA confinement due to their atomic flatness, precise height control, and excellent mechanical strength. Here, using femtosecond laser etching and wetting transfer, we fabricate graphene nanochannels down to less than 4.

Article Synopsis
  • Researchers created nanochannels using two-dimensional materials that exhibit unique fluid transport behaviors based on their crystal structure.
  • Black phosphorus was specifically used as the channel surface, revealing significant differences in ion transport along its crystal orientations, with the armchair direction showing a much higher energy barrier than the zigzag direction.
  • This anisotropic ion transport highlights the potential for new methods to control fluid movement in nanochannels by manipulating crystal orientation.
