Microporous water with high gas solubilities

Many biomedical and energy-related technologies require the transport of gas molecules through aqueous fluids but

the low solubility of gases in water imposes fundamental limitations. We use the laws of thermodynamics to create permanent microporosity and impart high gas solubilities to liquid water. By controlling the external and internal surface chemistry of microporous frameworks, we promote the formation of stable dispersions in water while maintaining dry networks of micropores that are accessible to gas molecules. As a result of their permanent microporosity, these aqueous fluids can concentrate gases, including oxygen (O2) and carbon dioxide (CO2), to much higher densities than are found in typical aqueous environments. These porous fluids can deliver oxygen to hypoxic red blood cells, highlighting one potential application of this new class of microporous liquids for physiological gas transport
