nanochannels
Microscopic fluid conduits
Nanochannels are extremely narrow passages or conduits measured in nanometers—billionths of a meter.
In biology, they appear in cell membranes, controlling the flow of ions and molecules.
In engineering and materials science, nanochannels are fabricated for filtration, drug delivery, or lab-on-a-chip devices: The researchers etched nanochannels into the silicon wafer.
