One aspect of the present invention relates to a silicon nanoporous membrane for oxygenating blood. The nanoporous membrane includes a first major surface, a second major surface, and a plurality of pores extending between the first and second major surfaces. The first major surface is for contacting a gas. The second major surface is for contacting blood and is oppositely disposed from said first major surface. The first and second major surfaces define a membrane thickness. Each of the pores is defined by a length, a width, and a height. Each of the pores is separated by a uniform interpore distance. 1. A silicon nanoporous membrane for oxygenating and/or removing carbon dioxide from blood , said nanoporous membrane comprising:a first major surface for contacting a gas;a second major surface for contacting blood and being oppositely disposed from said first major surface, said first and second major surfaces defining a membrane thickness; anda plurality of pores extending between said first and second major surfaces, each of said pores being defined by a length, a width, and a height, each of said pores being separated by a uniform interpore distance2. The nanoporous membrane of claim 1 , wherein each of said pores has the same bubble point to prevent or mitigate membrane failure through pore wetting.3. The nanoporous membrane of claim 1 , wherein said nanoporous membrane thickness is about 0.1 micrometer to about 50 micrometers.4. The nanoporous membrane of claim 3 , wherein said nanoporous membrane has a flattened claim 3 , sheet-like configuration.5. The nanoporous membrane of claim 1 , wherein each of said pores is slit-shaped.6. The nanoporous membrane of claim 1 , wherein each of said pores has a symmetrical cross-sectional profile.7. The nanoporous membrane of claim 6 , wherein each of said pores has a rectangular cross-sectional profile.8. The nanoporous membrane of claim 1 , wherein each of said pores has an asymmetrical cross-sectional profile.9. The ...
