Electrochemical study of redox enzymes and utilization in modified electrodes
Bioelectrochemisty is the branch of electrochemistry that deals with biological systems. One of the most intriguing category of biological molecules are redox enzymes. The mechanisms of many subcategories of such enzymes are still under investigation and electrochemical methods such as cyclic voltammetry and Fourier transformation alternate current cyclic voltammetry, could play a key role in uncovering these mechanisms and they could also provide useful information on thermodynamic properties such as their formal potentials. Also by immobilizing redox enzymes on electrodes there is the potential of constructing biosensors which can be suitable for the detection of different substrates. Moreover, by immobilizing enzymes on electrodes, there is also potential of managing direct electron transfer between the enzyme and the electrode, and thus facilitating enzyme reactions omitting expensive reagents that act as electron donors/acceptors, thus reducing the cost of biotransformation for the production of chemicals.
