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.
