The bis(octacyanophthalocyaninato)neodymium(III) was synthesized and its electrochemical behavior in N,N-dimethylformamide ( DMF ) was investigated by cyclic voltammetry (CV) and square wave voltammetry (SWV). Multiple redox reactions were observed on the cyclic voltammogram, although the voltammetric feature was complicated due to aggregation. With the aid of SWV, it was concluded that the redox potentials of the complex positively shifted by about 700 mV compared with potentials of the unsubstituted complex, which was ascribed to the strong electron-withdrawn effect of the substituted cyano group.

A novel bio electrode containing bacteria immobilized on clay mixed carbon paste electrode (Bactria-clay-CPE) is developed for detection and degradation of the phenolic solutions based on electrochemical techniques such cyclic voltammetry, square wave voltammetry, electroctrochemical impedence spectroscopy. The results obtained showed that bacteria-clay- CPE exhibited excellent electro-catalytic activity towards phenol. The recorded cyclic voltammogram shows that the oxidation of phenol is manifested by the appearance of four oxidation peaks.

We describe the design and synthesis of ferrocene dimers and trimers bridged by an oligothiophene spacer as both cathodic and anodic multiple redox-active organic–organometallic hybrid molecules. The electrochemical properties of all compounds were examined by cyclic voltammetry (CV). The voltammograms showed different multi-step, multi-electron redox reactions derived from multi-ferrocene fragments and the organic spacer. The results indicate that a number of thiophene rings in the spacer can be attuned to the redox potentials and the electron-transfer processes.

This study focuses on the compatibility of square wave voltammetry technique with new modified graphite pencil electrode to quantify Oxytocin. Ni-Nano particles and 1,5-diphenylcarbazide modifiers were quickly electro-deposited by cyclic voltammetry sweeping technique on the bare surface of a graphite pencil electrode. The electrochemical and morphological assessments were accomplished with cyclic voltammetry, square wave voltammetry and scanning electron microscopy techniques. The proposed electrochemical sensor revealed a good electro catalytic response to Oxytocin concerning the parameters α = 0.42, log Ks =3.44 and Γ = 8.72×10−10 in the optimized pH of 4 and the working potential of about 0.35 V. The new sensor also exhibited a linear response to Oxytocin over the concentration range of 125 to 350 nmolL−1 with the limit of detection of 41.53 nmolL−1. Moreover, the applicability of the proposed sensor was successfully examined and it became usable to determine Oxytocin accurately and precisely in real samples such as human blood serum sample without any serious side interference.

Convenient Synthesis

A convenient synthesis of 1,2-dicyanoferrocene (3) was developed by using 2,4-dinitrofluorobenzene as a dehydrating agent for the treatment of 1,2-ferrocenedicarbaldehyde dioxime (2) to give 3 in yields exceeding 80%. Compounds 2 and 3 have been characterized by IR and NMR (1H, 13C{1H}) spectroscopy and by electrochemistry (cyclic voltammetry and square-wave voltammetry). Furthermore, the molecular structures of 2 and 3 in the solid state have been determined by single-crystal X-ray crystallographic studies.

Amine Groups

Novel ECPs (electronic conducting polymers) based on amino β-styryl-substituted terthiophene (AST) were synthetized by direct electropolymerization. The ECPs were characterized by cyclic voltammetry, square-wave voltammetry, Fourier transform infrared (FTIR) spectroscopy, and X-ray photoelectron spectroscopy (XPS). The poly(amino β-styryl terthiophene) displayed cyclic and square-wave voltammograms with redox peaks that can be assigned to the aminophenyl moiety and the polyterthiophene backbone. The presence of free primary amine groups on the ECP film permitted further biological functionalization (i.e., covalent bonding of various bioreceptors on its surface). The electrochemical performance of Biotin grafted at the AST modified glassy carbon electrode was investigated to detect the Avidin protein in solution by cyclic voltammetry and square-wave voltammetry.Key words: electronic conducting polymer, electrode surface modification, biosensor, β-styryl-substitued terthiophene, functionalization, cyclic, square-wave voltammetry.
