This paper focuses on the use of PQQ-dependent enzymes (PQQ enzymes) in amperometrical biosensors and gives emphasis on their innovative designs and applications. The study covers some aspects in the evolution of biosensors based on PQQ enzymes. Main attention is focused on the electrochemical properties of PQQ enzymes as very promising materials for the formation of electrochemical biosensors. Immobilization approaches and redox mediators recently used in PQQ enzymes based biosensors are reviewed. The acceptance of polypyrrole as a very promising immobilization matrix for some PQQ enzymes is discussed.

Nitrobenzene occurs as a pollutant in wastewaters originating from numerous industrial and agricultural activities. It needs to be removed prior to discharge to sewage treatment works because of its high toxicity and persistence. In this study, we investigated the use of a bioelectrochemical system (BES) to remove nitrobenzene at a cathode coupled to microbial oxidation of acetate at an anode. Effective removal of nitrobenzene at rates up to 1.29 +/- 0.04 mol m(-3) TCC d(-1) (total cathodic compartment, TCC) was achieved with concomitant energy recovery. Correspondingly, the formation rate for the reduction product aniline was 1.14 +/- 0.03 mol m(-3) TCC d(-1). Nitrobenzene removal and aniline formation rates were significantly enhanced when the BES was supplied with power, reaching 8.57 +/- 0.03 and 6.68 +/- 0.03 mol m(-3) TCC d(-1), respectively, at an energy consumption of 17.06 +/- 0.16 W m(-3) TCC (current density at 59.5 A m(-3) TCC). Compared to those of conventional anaerobic biological methods for nitrobenzene removal, the required dosage of organic cosubstrate was significantly reduced in this system. Although aniline was always identified as the major product of nitrobenzene reduction at the cathode of BES in this study, the Coulombic efficiencies of nitrobenzene removal and aniline formation were dependent on the current density of the BES.

The design of an electrochemical glucose sensing device formed by the electrodeposition of multifunctional Au nanoparticles is reported here as a novel concept for an enhanced generic sensing platform. Initially gold nanoparticles (Au) were alternatively coated with a layer of positively charged redox polymer (ORP) and a negatively charged glucose oxidase (GOX) layer alternatively using layer-by-layer methodology to form multifunctional Au/ORP/GOX/ORP particles. The modification and stability of the Au nanoparticles was monitored by using UV-vis spectroscopy and zeta-potential measurements. The modified Au nanoparticles were electrophoretically deposited onto an electrode to produce an electrochemical glucose sensing device. A considerable influence of electrophoretic deposition time and potential was found on the sensing platform response. Preliminary responses to glucose addition showed an enhanced performance by applying an electrophoretic deposition potential of +1.2V vs. Ag/AgCl for 30 min. The observed response in the case of microelectrode geometry was in the range of mAcm(2). This work also shows that the presence of a second outer ORP layer on the functionalised Au nanoparticles improved the response.

Scientific research has advanced on different microbial fuel cell (MFC) technologies in the laboratory at an amazing pace, with power densities having reached over 1 kW/m(3) (reactor volume) and to 6.9 W/m(2) (anode area) under optimal conditions. The main challenge is to bring these technologies out of the laboratory and engineer practical systems for bioenergy production at larger scales. Recent advances in new types of electrodes, a better understanding of the impact of membranes and separators on performance of these systems, and results from several new pilot-scale tests are all good indicators that commercialization of the technology could be possible within a few years. Some of the newest advances and future challenges are reviewed here with respect to practical applications of these MFCs for renewable energy production and other applications.

A carbon fiber having a terminal glucose oxidizing microanode and an O2 reducing microcathode is propelled at the water-O2 interface. The electron current in the fiber is accompanied by a flux of hydrated protons that is so fast at the solution-air interface, where the viscous drag is small, that the fiber's velocity is 1 cm s-1.

Recombinant antibodies provide an emerging strategy in the development of new immunosensors. In particular, single chain antibodies (scFvs) can be isolated and expressed in bacterial systems that also allow their in vitro manipulation at the gene level. In this work, we present for the first time results of single-chain phage displayed antibodies combined with amperometric detection and its application as an immunosensor. The scFv is immobilized on a carbon electrode and used to capture and quantify its specific target antigen. We describe the detection of the sugar milk lactose, the bacteria Listeria monocytogenes, and the enzyme MtKatG, which is expressed by Mycobacteriumtuberculosis.
