First, why diamond? graphite sheet are nearly as strong and there is a well established technology to make them in the bulk. Second, What is a submicrometer gas? At that scale, surface effects are dominant. What about using capillarity to load a cylindrical bottle made from a nanotube? It seems that has been done for hydrogen, why to build atom by a atom a diamond structure? Diamond or not, carbon and high pressure oxygen are a noxious mix. Do you really would try to make such a complex, unstable, costly thing when fixing an ahemoglobin molecule to a carbon nanotube would do the same work at some $/kg?
