1. A gas exchanger apparatus comprising:
a substrate having a first side and a second side; a plurality of hydrophobic pillar-shaped structures with diameters between 1 and 100 nm disposed on the second side of the substrate with spaces between the pillar-shaped structures, wherein the pillar-shaped structures are disposed on the substrate in a configuration that leaves a plurality of fluid flow channels that are surrounded by the pillar-shaped structures, each of the channels having an inflow end and an outflow end, wherein each of the channels is wide enough for a fluid to flow through, and wherein the pillar-shaped structures are spaced close enough to each other to retain the fluid within the channels when the fluid is flowing through the channels, and wherein the substrate has a plurality of perforations that extend between the first side of the substrate and the second side of the substrate, each of the perforations being aligned with a respective one of the channels; a fluid inlet configured to supply fluid to the first side of the substrate, wherein the fluid inlet is in fluid communication with the perforations such that fluid that arrives via the fluid inlet will flow through the perforations and continue on through the channels; a fluid outlet configured to accept fluid that arrives from the outflow end of the channels; and a housing configured to house the substrate and the array of pillar-shaped structures, the housing having a gas inlet configured to route a gas into the spaces between the pillar-shaped structures and a gas outlet configured to route the gas away from the spaces between the pillar-shaped structures. |
