Applications of nanoporous alumina membranes

Nanoporous alumina membranes were electrochemically prepared in sulfuric or phosphoric acid. After preparation they were used for microfiltration of biological media, such as human red blood cells and bovine serum albumin. The filtration efficiency was studied by UV-Vis absorption spectroscopy. Additionally, nanoporus alumina substrate was filled by cobalt and used as catalyst for nanocarbon growth.
