“…The urgent task is to ascertain the possibility of using as an anode biocatalyst for BFC membrane fractions (MF) of microbial cells, containing a PQQdependent dehydrogenase. In a number of recent works was observed effect of direct electron transfer from a PQQ-dependent glucose dehydrogenase, immobilized onto multiwalled carbon nanotubes [46,47,48]. These data are the basis for the assumption that the use of biocomposite TRG/MF could provide a non-mediated catalysis of electrooxidation.…”

“…effective oxidation of MF was shown in [47,48]. We will note that unlike the expensive and complex techniques for receiving and purifying of enzymes, when receiving of MF is used a simpler procedure and, in this connection, the MF can be alternative to the use of enzymes in BFC.…”

“…The intact cells or their membrane fractions (MF were allocated in accordance with the procedure [47,48] were immobilized by inclusion in gel of a chitosan on the TRG-electrode surface. For this purpose, on the electrode was applied 20 mcl of MF or intact cells, diluted twice with buffer solution.…”

“…These concentrations encompassed both normal (3.6-6.1 mM) and abnormal (20 mM) glucose levels in human blood. The obtained detection limit was lower than that of other enzymatic glucose sensors based on different modified nanomaterials, while affinity of GOD was remarkably good (1.06 mM) [67,90,[98][99][100][101][102][103][104]. Furthermore, investigated the potentials of a miniaturised amperometric glucose biosensor completely embedded within an electrospun PU (polyurethane) membrane in order to withstand implantation [105].…”

Biological interactions in biosensors occur through different mechanisms, on the basis of the type of biological receptor elements employed therein that confer the biological specificity to the biosensors themselves (biocatalytic, biocomplexing or bioaffinity biosensors). The use of different transduction systems (amperometric, potentiometric, field-effect transistors, piezometric and conductometric) defines the mode of detection. The interest and relevance of nanomaterials in the fabrication of nanobiosensors lie in their extraordinary properties that make them ideally suited and very promising for sensing applications. The resulting nanobiosensors are capable of sensing analytes in traces with fast, precise and accurate biological identification through miniaturised and easy to use systems. These advanced sensors are also characterised by lower detection limits, higher sensitivity values and high stability, and can further offer multi-detection possibilities. These exceptional features make nanobiosensors as the favourite tools in quality control, food safety, and traceability for their capacity of revealing and warning people against the presence of pathogens, toxins and pollutants, as well as bioterrorism agents. Despite the outstanding properties of these nanobiosensors, however, the efficiency of the biorecognition agent and the number of biorecognition sites available for interacting with target analytes can limit the sensitivity of this kind of sensors. The number of available biorecognition sites is directly related to the surface area of the sensor. Electrospinning technology can significantly increase the sensitivity of biosensors by replacing the typical planar interactive surface of conventional biosensors with a mat of electrospun nonwoven nanofibres, thereby taking advantage of the ultrahigh surface area offered by electrospun nanofibres. Moreover, adjusting the electrospinning process to produce

“…Prussian blue deposited carbon nanotubes hybrids, combining the efficient facilitation effect of CNTs on electron transfer (Tang et al, 2004;Guan et al, 2005;Huang et al, 2006;Tsai and Tsai, 2009) with the effective low-potential electron transfer mediation effect of Prussian blue toward the reduction of H 2 O 2 (Ahmadalinezhad et al, 2009;Chiu et al, 2009;Wang et al, 2009;Li et al, 2010), are attracting particular interest in the area of electrochemistry (Zhai et al, 2009;Zhang et al, 2009).
