Abstract
A method for fabricating calcite channels in a nanofluidic device is described. A porous membrane is attached to a substrate. Calcite is deposited in porous openings in the porous membrane attached to the substrate. A width of openings in the deposited calcite is in a range from 50 to 100 nanometers (nm). The porous membrane is etched to remove the porous membrane from the substrate to form a fabricated calcite channel structure. Each channel has a width in the range from 50 to 100 nm.
