摘要： A recloseable biosensor is provided that comprises a substrate, a sample site positioned on the substrate, and an openable and recloseable cover coupled to the substrate. The cover is operative to selectively block access to the sample site. The cover includes a fixed end coupled to the substrate, an opposite free end, and a middle portion extending across the sample site. The middle portion is releasably and recloseably adhered to the substrate.

摘要： A biosensor is provided that comprises a substrate, a sample site positioned on the substrate, a cover coupled to the substrate, and biocide positioned between the substrate and the cover. The biosensor may also include desiccant. The cover is operative to selectively block access to the sample site. The cover includes a fixed end coupled to the substrate, an opposite free end, and a middle portion extending across the sample site. The middle portion is releasably and recloseably adhered to the substrate.

摘要： A biosensor is provided in accordance with this invention. The biosensor includes a bottom section with an edge and a flange extending from the edge, a top section supported on the bottom section and having an edge and flange extending from the edge in alignment with the flange of the bottom section. The flanges of the top and bottom sections cooperate to form a capillary channel, and first and second electrodes. Additionally, the first electrode is positioned on the flange of the bottom section in the capillary channel and the second electrode is positioned on the flange of the top section in the capillary channel.
