The microfabrication protocol for silica-GEMs entails designing, photolithography, chrome sputtering, and isotropic and anisotropic etching. Despite the water loving nature of silica, water does not intrude silica-GEMs on submersion. In fact, they robustly entrap air underwater and keep it intact even after six weeks (106 seconds). On the other hand, silica membranes with simple cylindrical pores spontaneously imbibe water ( less then 1 s). These findings highlight the potential of the GEMs architecture for separation processes. Wh
