Enzymatic bioelectrocatalysis is being increasingly exploited to better understand oxidoreductase enzymes, to develop minimalistic yet specific biosensor platforms, and to develop alternative energy conversion devices and bioelectrosynthetic devices for the production of energy and/or important chemical commodities. In some cases, these enzymes are able to electronically communicate with an app...

Bioelectrocatalysis is a phenomenon concerned with biological catalysts, which accelerate the electrochemical reactions. Bioelectrocatalysis has been widely explored by the research community in various directions. Enzymes can catalyze different chemical reactions in living organisms by enzymes as the most important biological catalysts. These enzymatic biocatalysts are commercially available a...

Enzymatic bioelectrocatalysis relies on immobilizing oxidoreductases electrode surfaces, leading to different applications, such as biosensors [...]

We report the usage of DNA hydrogels for enzyme entrapment in an enzymatic biobattery. With the recent advancements in DNA nanotechnology, the incorporation of DNA materials to bioelectrocatalytic electrodes holds great promise to improve the performance of bioelectrocatalysis-based devices.

Electron transfer (ET) in sulphite oxidase (SOx), a heme- and molybdopterin cofactor-containing enzyme, was studied spectroelectrochemically using capillary gold electrode modified with aldrithiol. Direct electron exchange between SOx and the surface of modified gold was observed, with a formal potential of -115 mV vs. Agmid R:AgCl, KCl(sat) at pH 7.0. This value agreed well with that previousl...

Bioelectrocatalysis using redox enzymes appears as a sustainable way for biosensing, electricity production, or biosynthesis of fine products. Despite advances in the knowledge parameters that drive efficiency enzymatic electrocatalysis, weak stability bioelectrodes prevents large scale development bioelectrocatalysis. In this review, starting from understanding protein instability, we will dis...

Submit Manuscript | http://medcraveonline.com treatment approach [1,2]. Biofuel cells can be divided into two main categories: enzymatic fuel cells (EFC) and microbial fuel cells (MFC). In both, oxidation of a given “fuel” occurs at the anode combined with a reduction of final electron acceptor at the cathode [3] . The potential difference between the two electrodes is the driving force of the ...
