This work demonstrates the creation of free-standing, nanoporous SiC membranes, and their ability to pass molecules of biologic interest. We have shown that proteins up to 29000 Daltons in molecular weight can pass through porous SiC. Also, we have shown that porous SiC resists protein adsorption comparable to the best commercially available polymer membrane that has been specifically developed to avoid protein adsorption.
