Polyaniline/zirconium oxide (PANI/ZrO 2) nanocomposites have been synthesized by incorporating ZrO 2 nanoparticles into the PANI matrix via liquid-liquid interfacial polymerization method. The composite formation and structural changes in PANI/ZrO 2 nanocomposites were investigated by powder X-ray diffraction (PXRD), scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FT-IR). PXRD pattern of PANI/ZrO 2 nanocomposites exhibited sharp and well-defined peaks of monoclinic phase of ZrO 2 in PANI matrix. SEM images of the composites showed that ZrO 2 nanoparticles were dispersed in the PANI matrix. The FT-IR analysis revealed that there was strong interaction between PANI and ZrO 2. AC conductivity and dielectric properties of the nanocomposites were studied in the frequency range, 50-10 6 Hz. AC conductivity of the nanocomposites obeyed the power law indicating the universal behaviour of disordered media. The nanocomposites showed high dielectric constant in the order of 10 4 , which could be related to dielectric relaxation phenomenon. Further, the materials were checked for their supercapacitance performance by using cyclic voltammetry (CV), chronopotentiometry (CP) and electrochemical impedance spectroscopy (EIS). Among the synthesized nanocomposites, PANI/ZrO 2-25 wt.% showed a higher specific capacitance of 341 F g −1 at 2 m Vs −1 and good cyclic stability with capacitance retention of about 88% even after 500 charge-discharge cycles.

“…Other methods were based on and voltammetry [11]. Few methods were based on the fabrication of nanomaterialbased sensing methods [12][13][14]. According to the previous methods, it can be seen that most of them are based on using expensive and sophisticated techniques, this encourages us to develop a simple method for the assay of sumatriptan in the pharmaceutical samples.…”

Objective: To develop a sensitive, fast and selective method for the determination of sumatriptan succinate (SUM) in pharmaceutical samples. Methods:The method is based on measuring the synchronous fluorescence of SUM using ∆λ of (12 0 nm) and at a wavelength of excitation and emission of 230 and 325 nm respectively, using Agilent Technology, Cary eclipse, G9800AA model Luminescence spectrometer. Effect of variables on fluorescence emission intensities was studied such as solvent, surfactant, and pH. The proposed method was validated in term of linearity, limit of detection as per the international conference on harmonization guidelines ICH Q (R1). Results:The linearity of the method was obtained with a wide range of (50-150) ng/ml with a high value of correlation coefficient value of (0.992). Limits of detection (LOD) and limits of quantitation (LOQ) were found to be 16.3 and 49.5 ng/ml respectively, the mean recovery was found to be 99.1% with low relative standard deviation (% RSD). The method was also compared statistically with the reference method using t-test and f-test, the results show no difference either in pure or pharmaceutical tablets. Conclusion:The obtained results revealed that the developed method can be applied successfully for the determination of SUM in drug formulations samples with good accuracy and precision.

“…Many advantages such as very low background current, low cost, large potential window, simple surface renewal process, and easiness of miniaturization of carbon paste electrode (CPE) are widely applicable in both electrochemical studies and electroanalysis. In addition, easy fabrication of the electrode can be achieved by incorporating different substances during paste preparation which results in the so-called modified electrode with desired composition and predetermined properties (Khoobi A. et al 2013;Mokhtari A. et al 2012;Díaz C. et al 2013;Gholivand M.B. and Mohammadi-Behzad L. 2014;Mazloum-Ardakani M. et al 2010;Raoof J.B et al 2007;Dönmez S. et al 2014).…”

Background: A set of pyrimidine nucleobase present in all living systems as a component of nucleic acid constitutes uracil together with thymine and cytosine. A diverse physiological activity is exhibited by many N-substituted uracil derivatives. In oncology, 5-FU is widely used as an important anticancer drug. Methods: Electrochemical behavior was studied using cyclic voltammetric method, and the analytical application was studied using differential pulse voltammetric method. Solution pH has been measured by pH meter. Results: The process on the surface of electrode was found to be irreversible and diffusion controlled. The charge transfer coefficient, heterogeneous rate constant, and the number of electron transferred were calculated. Possible reaction mechanism taking place on the surface of electrode was proposed. Calibration plot constructed using differential pulse voltammetric technique was used for quantitative analysis in pharmaceutical and human urine sample. Limit of detection (LOD) and limit of quantification (LOQ) were calculated to be 12.25 and 40.8 nM, respectively. Conclusions: In the present work, we described the electrochemical behavior of anticancer drug and its determination in human urine and pharmaceutical samples. The method shows the development of a sensor for selective and sensitive determination of 5-FU.
