Angstrofluidics: Walking to the Limit

Angstrom-scale fluidic channels are ubiquitous in nature and play an important role regulating cellular traffic, signaling, responding to stimuli. Synthetic angstrom now a reality with the emergence of several cutting-edge bottom-up top-down fabrication methods. In particular, use atomically thin 2D materials nanotubes as components build conduits has pushed limits scale. Here, we provide overview recent developments methods for nano- angstrofluidic while categorizing them on basis dimensionality (0D pores, 1D tubes, slits), along latest advances measurement techniques. We discuss ion transport governed by various stimuli these variation ionic mobility, streaming power, osmotic power pore size across all dimensionalities. Finally, highlight unique future opportunities development smart devices.
