Abstract: Articles (i.e., first articles) with a photoiniferter covalently attached at multiple locations of a substrate having an inorganic oxide coating on a polymeric film are provided. These first articles can be used to form other articles (i.e., second articles) with multiple polymers covalently attached to the inorganic oxide coating of the substrate. The attached polymers are in the form of polymeric brushes extending from the surface of the inorganic oxide coating of the substrate. The polymeric brushes can be functionalized with groups that can bind compounds used in chemical and/or biochemical assays including pharmaceutical assays. The second articles can be used in various analytical devices.

Abstract: Described herein is methacrylate copolymer derived from: a (meth)acrylate monomer comprising a second terminal olefin group; an alkyl methacrylate monomer wherein the alkyl group comprises 1 to 4 carbon atoms; a mono(meth)acrylate monomer comprising a low-surface-energy group, wherein the low-surface-energy group comprises a perfluorinated alkyl group, a perfluorinated polyether group, or a silicone group; and a RAFT agent. Such copolymers can be used to make liquid compositions, which may then be used to generate tooling for nanoimprint or transfer lithography.

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.
