Abstract: Enzyme-based electrochemical sensors comprising transition metal complexes of iron, cobalt, ruthenium, osmium, and vanadium are described. The transition metal complexes can be used as redox mediators and include substituted or unsubstituted pyridyl-imidazole ligands. Transition metal complexes attached to polymeric backbones are also described.

Abstract: A carpet fastening system in which a fastening strip 100,200 & 300) is affixed to the back-side of the wall board (10) or the wall baseboard (8), preferably with the wall engagement portion (101, 201 & 301) being substantially flat, presenting either a flat, face-to-face, extended surface interface (FIGS. 1A & 2A) with the back-side of the wall or at least preferably a continuous or at least substantially extended edge (FIG. 3A) in engagement with the back-side, bottom edge of the wall baseboard. For ease in installation, the fastening strips may be installed either at the same time as the baseboards are installed or even when the wall boards are being installed. As a result of engaging the back-side of the wall the fastening strips are firmly affixed to the wall and provide secure, strong affixation to the wall, securely anchoring the strips and hence the carpet, preventing any migration of the carpet during its typically expected life-time and longer. The embodiments are described (FIG. 1+, FIG. 2+ and FIG.
