“…Immediately after it was shown that the Gr has high electronic conductivity and relatively easily produced, the stream of researches directed on attempts of its application for bioelectrodes construction considerably grew [83]. The Cr could be received mechanically by removal of the graphite layers or by chemical way -vapour-deposition method; graphene materials are received by chemical synthesis.…”

“…(17)(18)(19) For example, an enzyme in the biorecognition layer acting as an electroactive substance was utilized in a multichannel electrochemical biosensor. (6,15,20) Here, detection occurs owing to the physicochemical transduction that provides a measurable signal. Generally, a native enzyme is used as a biorecognition component, i.e., as an analyte (2,12,22) or an inhibitor.…”

Graphene possesses a high surface-to-volume ratio, which enables biomolecules to attach to it for bioelectronic applications. In this article, first, the classification and applications of bioelectronic devices are briefly reviewed. Then, recent work on real fabricated graphenebased bioelectronic devices as well as the analysis of their architecture and design using a computational approach to their charge transport properties are presented and discussed. A comparison to nongraphitic bioelectronic devices is also given. On the macroscale level, the design of devices is elaborated on the basis of a finite element analysis (FEA) approach, and the impact of design on the performance of the devices is discussed. On the nanoscale level, transport phenomena and their mechanisms for different design categories are elaborated on the basis of the density functional theory (DFT) and other quantum chemistry calculations. The calculated and measured charge transport properties of graphene-based bioelectronic devices are also compared with those of other available bioelectronic devices.

“…Devices such as fuel cells [1], supercapacitors [2] and batteries [3] need high surface area electrodes, high electrical conductivity and controllable porosity among other properties. High surface area carbonaceous materials, such as carbon nanotubes (CNT) [4,5], carbon nanofibers (CNF) [6,7] or graphene [8,9], have attracted great interest due to their excellent electrical conductivity and mechanical properties. Graphene has been intensively studied in the latter years, focusing on its physicochemical and electrochemical properties to utilize it as a catalytic support on the electrode surface [10,11].…”

These authors contributed equally to the workElectrochimica Acta 191 (2016) 500-509 ; http://dx.doi.org/10.1016/j.electacta.2016.01.101 ABSTRACT High surface area graphene electrodes were prepared by simultaneous electrodeposition and electroreduction of graphene oxide. The electrodeposition process was optimized in terms of pH and conductivity of the solution and the obtained graphene electrodes were characterized by Xray photoelectron spectroscopy, Fourier transform infrared spectroscopy, scanning electron microscopy and electrochemical methods (cyclic voltammetry and impedance spectroscopy).Electrodeposited electrodes were further functionalized to carry out covalent immobilization of two oxygen-reducing multicopper oxidases: laccase and bilirubin oxidase. The enzymatic electrodes were tested as direct electron transfer based biocathodes and catalytic currents as high as 1 mA/cm 2 were obtained. Finally, the mechanism of the enzymatic oxygen reduction reaction was studied for both enzymes calculating the Tafel slopes and transfer coefficients.2
