“…(1) and (2), has not been completely established yet. The direct electron transfer process might be very complicated and the dominant pathway seems to depend on the method of electrode preparation, glucose concentration and applied potential [8,13]. However, it has been reported that the presence of oxygen may induce a poor response of the biosensor towards glucose because of the competition between oxygen, Eq.…”

“…Horseradish peroxidase-based enzyme systems, on the other hand, provide a specific detection of H 2 O 2 but always lack practical stability. The addition of mediators (such as metal hexacyanoferrates, − methyl viologen, tetrathiafulvalene tetracyanoquinodimethane, luminol, etc.) that can operate at relatively lower potentials is a good alternative for the metal-based biosensors.…”

Iron-enriched industrial waste cinder (CFe*) has been recycled for efficient and stable anchoring of Ru(CN)6(4-) to the formation of a hybrid ruthenium purple complex. The cinder/ruthenium purple hybrid-modified carbon paste electrode (designated as CPE/CFe*-RP) was worked out for hydrodynamic analysis of H2O2 at a low detecting potential of 0.0 V versus Ag/AgCl in pH 7 ammonium buffer solution. The highly active, selective, and stable electrocatalytic system with a function similar to peroxidase enzyme shows a linear calibration curve up to 0.8 mM H2O2 at a rotation rate of 3600 rpm with slope and detection limit (S/N = 3) of 0.11 microA/microM and 33 nM, respectively. Interference by direct electrochemical oxidation of easily oxidizable substances can be prevented as a result of the low detecting potential of the working system. A glucose biosensor was further constructed by coating with glucose oxidase and Tosflex on the CPE/CFe*-RP (denoted as CPE/CFe*-RP/GOx/Ts). The proposed CPE/CFe*-RP/GOx/Ts with a two-layer configuration, that is, enzyme and protecting layers, exhibits good operational performance in terms of response time, linearity, detection limit, and lifetime.
