Abstract: Infiltrated three-dimensional articles are provided. An article includes a first polymeric material having an exterior surface and an interior volume; and a second polymeric material that is a thermoplastic polymer or a reaction product of a polymerizable composition disposed in at least a portion of the interior volume of the first polymeric material to a depth from the exterior surface. Methods of making the articles are provided. A method includes curing a photopolymerizable composition containing at least one reactive component and at least one photoinitiator to form an additive manufactured three-dimensional structure of a first polymeric material having an exterior surface and an interior volume. The method further includes contacting at least a portion the three-dimensional structure with a fluid to form an infiltrated structure; and curing or drying the fluid of the infiltrated structure to form an infiltrated three-dimensional article.

Abstract: An article includes a flexible structured film with a first major surface and a second major surface, wherein a first major surface of the flexible structured film has a plurality of posts separated by land areas, and the posts have an exposed surface. An anti-biofouling layer resides in the land areas, and the anti-biofouling layer has a methylated surface. An inorganic layer is on the exposed surfaces of the posts, wherein the inorganic layer includes a metal or a metal oxide. An analyte binding layer is on the inorganic layer, wherein the analyte binding layer is chosen from a reactive silane, a functionalizable hydrogel, a functionalizable polymer, and mixtures and combinations thereof. An exposed surface of the analyte binding layer includes at least one functional group selected to bind with a biochemical analyte.
