Voltammetric behavior of muscle relaxant dantrolene sodium (DAN) was studied and the voltammetric methods for its determination using polished and mercury meniscus modified silver solid amalgam electrodes (p-AgSAE and m-AgSAE) as well as using bismuth film electrode (BiFE, ex situ plating on GCE) have been proposed. These working electrodes represent the most commonly used alternatives to mercu...

A novel voltammetric sensor based on gold nanoparticles (GNPs) and single-walled carbon nanotubes (SWNTs) composite was developed. The nanocomposite modified electrode was characterized using atoms force microscope (AFM). The electrochemical behavior of meclofenoxate hydrochloride (MFX) was investigated on this sensor. The results indicated that the GNPs/SWNTs modified electrode exhibited effic...

The behavior of chlordiazepoxide has been studied using dc-polarography at dropping mercury electrode (DME) and cyclic voltammetry at glassy carbon electrode (GCE). In Britton-Robinson buffers, the drug developed three reduction irreversible waves in acidic solutions, and only two waves in alkaline media. The adsorptive stripping voltammetric behavior of chlorodiazepoxide was studied at GCE, an...

A novel experimental method was developed to study the origin of the voltammetric response of human prostate cancer (PC-3) cell suspension as a model in consideration of the biological characters of living cells. The presence of guanine and xanthine in the cell eluent secreted by the living cells was verified by HPLC assay with a DAD system and chemometric method. Comparative studies of voltamm...

In this study, pencil graphite electrode was modified using conductive polypyrrole (Ppy) and grapheme (GF) nanocomposite for electrochemical determination of insulin. Electrochemical behavior of insulin on PGE was investigated using cyclic voltammetric (CV) and differential pulse voltammetric (DPV) and chronoaprometry (CA) methods. Several effective parameters including pH, concentration, and s...

the adsorptive behavior of the immunosuppressive agent tacrolimus was studied by cyclic and differential-pulse voltammetry on a hanging mercury drop electrode (hmde). the drug was accumulated at hmde and two well-defined peak currents were obtained at -1353 and -1417 mv vs . sce (saturated kcl) in borate buffer (ph 10.0) + 0.1 kcl solution. a voltammetric procedure was developed for the determi...
