Metal nitride materials are garnering interest in many fields including electrochemistry, although they are still at an early stage of investigation and underexplored. This mini review provides insights on the latest advancements in the field of electroanalytical chemistry based on metal nitride materials, specifically focusing on the best performi...
Article
Covalent coupling between a surface‐exposed cysteine residue and maleimide groups was used to immobilize variants of Myriococcum thermophilum cellobiose dehydrogenase (MtCDH) at multiwall carbon nanotube electrodes. By introducing individual cysteine residues at particular places on the surface of the flavodehydrogenase domain of the flavocytochrom...
Article
In this work we extended the generic approach for the site-directed immobilization of enzymes based on maleimide\thiol coupling of engineered enzymes to the oriented immobilization of variants of bilirubin oxidase from Magnaporthe oryzae (MoBOD) to electrodes. We show that this approach leads to the stable attachment of the enzyme to the electrode...
Article
It is widely claimed that native GOx undergoes direct electron transfer (DET) at nanostructured electrodes. In this paper we argue that the vast majority, if not all, of these claims are incorrect. We present results for GOx adsorbed on MWCNTs, a typical nanostructured electrode. We show that the surface redox peaks usually attributed to DET to GOx...
Thesis
This thesis studies the conditions required to achieve direct electron transfer and the experimental tests needed to unequivocally demonstrate that it occurs. Many publications claim to observe direct electron transfer to redox enzymes (for example in the case of glucose oxidase) but the evidence presented is often incomplete and unconvincing. The...

“Kinetics and Electrocatalytic Properties of Cellobiose Dehydrogenase Covalently Immobilised at Electrode Surfaces”
Article
Stable, site-specific immobilization of redox proteins and enzymes is of interest for the development of biosensors and biofuel cells, where the long-term stability of enzymatic electrodes as well as the possibility of controlling the orientation of the biomolecules at the electrode surface have a great importance. Ideally, it would be desirable to...

This study suggests a new approach for the construction of a stable glucose biosensor based on the covalent immobilisation of cysteine genetically engineered CDH from Myriococcum thermophilum onto modified multi-walled carbon nanotubes (MWCNTs). The carbon nanotubes were modified with maleimide groups by using a method introduced in 2014 by Wright...

Covalent immobilization of engineered Cellobiose Dehydrogenase from Myriococcum thermophilum

Direct electron transfer of redox enzymes that are close to the electrode surface is usually very slow. It may even prove impossible because of the shielding of the active side and/ or redox-active cofactors of the enzyme by the surrounding insulating protein shell. This problem can be resolved by introducing multi-cofactor enzymes in which the ove...
Poster
This study suggests a new approach for the construction of a stable glucose biosensor based on the covalent immobilisation of Cellobiose Dehydrogenase from Myriococcum thermophilum (MtCDH) at carbon-based electrodes. Cellobiose Dehydrogenase is a monomeric protein consisting of two domains containing two active sites: heme and FAD. Carbohydrates su...
Article
The new cobalt (II), nickel (II) and copper (II) complexes with 2,3-di(thiobutane) aniline in the coordination sphere were prepared. All the complexes were characterized by IR, UV-vis. Spectroscopy, conductivity and magnetic measurements and some of them by metal content. Conductivity data in DMSO showed that some complexes are 1:2 (M:L) electrolyt...

The electrical behaviour of association phenomena of tetra aqua (1,10 _ phenanthroline) zinc(II) chloride in the methanol-water mixture has been investigated by precise conductance measurements at 288.15 - 308.15K which can give information about ion-ion and ion-solvent interactions in solution. The limiting molar conductance λM2+, the association...

ABSTRACT The electrical behaviour of mixed ligand complex of Fe(II) in different percentage of binary mixture of methanol and water at different temperatures can give information about ion-ion and ion-solvent interaction in solution so the limiting molar conductance , KA the association constant and (R) the main distance between ions in solution as...

The hydrodynamic behaviour of tetra aquo-1,10-phenanthroline cobalt (II) chloride in the methanol-water mixture has been investigated by precise conductance measurements at 288.15-308.15 K. The limiting molar conductances (Λo), ion association constant KA of the electrolyte and the main distance between ion in solution (R) have been evaluated by Le...
Thesis
Radiolysis of thymine and uracil in aqueous solutions have been preformed. Formations of peroxides on both thymine and uracil have been investigated by using different pH conditions. The effect of pH on the decay of the produced organic peroxides under individual pH irradiation condition has been monitored. Results indicate that the organic peroxid...
