Characteristics of third-generation glucose biosensors based on Corynascus thermophilus cellobiose dehydrogenase immobilized on commercially available screen-printed electrodes working under physiological conditions

Coupling of an enzymatic biofuel cell to an electrochemical cell for self-powered glucose sensing with optical readout

“…However, the oxidation of other mono-and disaccharides occur with lower catalytic efficiencies. Therefore, this system could be used for the analysis of a single sugar in different samples where glucose is a major constituent including biological fluids [18,19]. For the adequate immobilization of an enzyme to an electrode and in order to obtain a substrate-dependent current flow, the prosthetic group of the enzyme has to be electrochemically recycled at the electrode surface [20].…”

Exploring Properties of a Hyperthermophilic Membrane‐Bound Hydrogenase at Carbon Nanotube Modified Electrodes for a Powerful H2/O2 Biofuel Cell

“…This procedure is commonly used in the case of stabilization of bioelectrodes. As examples nitrite, l-arginine or glucose biosensors were constructed based on cross-linking by means of glutaraldehyde of nitrite reductase, arginase and urease, and cellobiose dehydrogenase, respectively [43][44][45]. Cross-linking by glutaraldehyde was supposed to suppress leakage of the enzymes.…”

Recent developments in recognition elements for chemical sensors and biosensors

“…The cellobiose dehydrogenase is a versatile recognition element for biosensors that can detect carbohydrates, such as glucose and lactose [38,39,45,72]. In turn, AChE is an enzyme commonly used in biosensors for detection of organophosphorus pesticides, since its catalytic activity (hydrolysis of acetylcholine to thiocholine) is inhibited by trace amounts of such compounds.…”
