The electron transfer of redox-active sites of immobilised haemoglobin (Hb) has been studied by voltammetric experiments. The electrode surface was modified by nanoparticles (NPs) to make a suitable substrate for electric wiring of protein molecules and efficient electron transferring. Hence, the Hb/zinc oxide NPs/platinum electrode was prepared by chronoamperometric deposition of the NPs and immobilisation of protein molecules. The electrochemical behaviour of the prepared biosensor was quasi-reversible and showed a pair of redox peaks with a formal potential (E 0′) of 214 mV. Additionally, the electron transfer rate constant (k s) of immobilised Hb was about 0.621 s −1. Biocatalytic reduction of hydrogen peroxide was also examined on the prepared biosensor. Result indicated to good sensitivity, wide linear range and low detection limit of 6 μM.

“…The role of nanomaterials as a constituent of the electrode could assist electron transfer between the analyte and the electrode surface [17]. Various nanomaterials because of their unique properties have attracted great interest in numerous fields [18][19][20][21][22]. The subtle electronic properties suggest that carbon nanotubes have the ability to promote electron-transfer reactions [23][24][25].…”

Amlodipine besylate and atorvastatin calcium have been determined by the simultaneous voltammetric method at a multi-walled carbon nanotubes:graphite (MWCNTs:G) paste electrode. In comparison with a glassy carbon electrode, the prepared electrode showed an increase in the peak current because of the high electroactive surface area and excellent electronic conductivity of MWCNTs. The dependence of currents and potentials on pH were investigated for these components at the surface of the MWCNTs:G paste electrode. Differential pulse voltammetry was applied as a sensitive technique for simultaneous determination of the drugs in commercial tablets. By anodic differential pulse voltammetry, the calibration plot was linear in the range of 2.5-100 µg/ml with standard deviation between 2.7-7.1 and 1.8-8.3% for amlodipine and atorvastatin, respectively. The detection limit was 1 µg/ml at the prepared electrode in the buffered solution pH 6.

Recently, researchers are considerably focused on nanostructured materials because of their unique optical, electronic, magnetic, and catalytic properties [12][13][14][15][16][17]. By reducing the grain size of known materials, better physicochemical and mechanical properties can be obtained.…”

In this study, a method to identify the impedance of the sample composed of Sn02 nanowires (NWs) has been presented. The studied sensor structures were based on one dimensional (ID) Sn02 NWs grown by thermal deposition on silicon substrate. The topography of Sn02 NWs was investigated by means of scanning electron microscopy (SEM).The results of qualitative and quantitative analysis in selected micro region have been presented. Furthermore, the electrical properties of the NWs were measured. The base of the measurement comprised impedance spectroscopy, Pade data approximation restrained by passivity condition. This study demonstrates that it is possible to separate the characteristic parameters for various transport phenomena in the NW. R EFERENCES[1] A.
