Ligand-directed targeting and capturing of cancer cells is a new approach for detecting circulating tumor cells (CTCs). Ligands such as antibodies have been successfully used for capturing cancer cells and an antibody based system (CellSearch(®)) is currently used clinically to enumerate CTCs. Here we report the use of a peptide moiety in conjunction with a(More)
A two-step synthetic process is reported to fabricate porous ceria membranes by anodization of cerium metal foils with subsequent calcination. ''Ribbon-like'' structures were found to form the backbones of these porous frameworks. The hydrophobic nature of these membranes was revealed by water contact angle measurements. Nanoporous membrane structures are(More)
