“…Besides for sustainable green energy production, the enlargement of system operational with electron carrier powerfully immobilized at biodevice is being desirable. Mediator immobilization has been conducted using a several procedures, such as direct covalent attachment through the formation of lm deposited electrochemically on the surface of electrode [40], mediator electropolymerization of the electrode surface [41,42] or just only adding and mixing into carbon pasta. The advantages of this technique are has large catalytic response and longterm perform stability [42].…”

Microbial desalination cell (MDC) built on bio-catalytic devices modification has been studied for sea water desalination using Saccharomyces cerevisiae as biocatalyst. Here we focussed the modification of anode and this study has been confirmed that bio-catalytic devices maintenance could contribute to the long-term MDC perform during desalination process. The goal of this study is to provide and develop a sea water desalination system without requiring an energy support by applying modification of anode as electron acceptor, and the different potential charges that occur between anode and cathode can plays as driving force for electro dialysis of sea water desalination. Several types of bio-catalytic devices modification have been conducted, i.e. by immobilization of mediator, immobilization of biocatalyst or a combination of both. The optimization of each device has been characterized by cyclic voltammetry, Chronoamperometry, and applied in Microbial fuel cell prior observed in MDC. The concentrations of ion salt migration have been determined by Ion Exchange Chromatography. The profiles of surface device have been detected by Scanning electron microscope and Energy Dispersive X-ray spectroscopy. Results shows that the modification of anode could be a promising method for bioelectricity generation delivered from MDC which as simultaneously produce an electricity and sea water desalination and provide a green chemistry technology.

“…Ghica's group used PNR-mediated enzyme biosensors for heavy metal determination [28]. Dilgin's group used glassy carbon electrodes, which are modified with PNR, for photoelectrocatalytic oxidation of NADH [29]. Zhong's group mainly focused on the properties of PNR film as support for Pt particles in the electrocatalytic oxidation of ethanol [30].…”

CuO shuttle-like nanocrystals on a poly(neutral red) glassy carbon electrode (nano-CuO/PNR/GCE) has been fabricated and used to simultaneously detect guanine and adenine. The sample is characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), and differential pulse voltammetry (DPV). It has been shown that the oxidation peak current of guanine and adenine could be greatly enhanced with the nano-CuO/PNR/GCE. Under optimal conditions, the anodic peak current of differential pulse voltammetry is proportional to the concentration of the guanine and adenine in the range of 0.05 to 3.0 μM. The corresponding detection limits are 1.6×10 −2 μM for guanine and 2.3×10 −2 μM for adenine (S/N=3). The nano-CuO/PNR/ GCE exhibits good storage stability and reproducibility for practical application. It could be applied to simultaneously determination of guanine and adenine for the samples with good anti-interference ability.

“…These similar values show that poly(o-phenylenediamine)-modified electrodes can be used for the oxidation of both nicotinamide adenine dinucleotides. The photoelectrocatalytic oxidation of NADH has been investigated at a GC electrode modified with poly (neutral red) and poly(toluidine blue) (Dilgin et al 2007(Dilgin et al , 2011. The modified electrodes showed electrocatalytic as well as photo-electrocatalytic activity towards NADH.…”

The applicability of dissolved redox mediators for NAD(P) + regeneration has been demonstrated several times. Nevertheless, the use of mediators in solutions for sensor applications is not a very convenient strategy since the analysis is not reagentless and long stabilization times occur. The most important drawbacks of dissolved mediators in biocatalytic applications are interferences during product purification, limited reusability of the mediators, and their cost-intensive elimination from wastewater. Therefore, the use of immobilized mediators has both economic and ecological advantages. This work critically reviews the current stateof-art of immobilized redox mediators for electrochemical NAD(P) + regeneration. Various surface modification techniques, such as adsorption polymerization and covalent linkage, as well as the corresponding NAD(P) + regeneration rates and the operational stability of the immobilized mediator films, will be discussed. By comparison with other existing regeneration systems, the technical potential and future perspectives of biocatalytic redox reactions based on electrochemically fed immobilized mediators will be assessed.
