Description A new chemically modified electrode is constructed based on iron(III) doped zeolite modified carbon paste electrode (Fe3+Y/ZCME). The electrode was evaluated as a sensor for sub-micromolar determination of tryptophan (Trp), uric acid (UA) and ascorbic acid (AA) in aqueous solutions. The measurements were carried out by application of the differential pulse voltammetry (DPV) method in phosphate buffer solution with pH 3.5. Iron(III) loaded in zeolite can increase anodic peak currents by adsorption of Trp, UA and AA on electrode surface The analytical performance was evaluated with respect to the carbon paste composition, pH of solution, accumulation time and accumulation potential. The prepared electrode shows voltammetric responses with high sensitivity and selectivity for Trp, UA and AA in optimal conditions, which makes it very suitable for simultaneous determination of these compounds. The linear calibration range for AA in the presence of 50 M UA and 50 M Trp was 0.6 M to 100 M, with a correlation coefficient of 0.9992, and a detection limit of 0.21 M (S/N = 3). A linear relationship was found for UA in the range of 0.3–700 M containing 10 M AA and 50 M Trp, with a correlation coefficient of 0.9990 and a detection limit of 0.08 M. The linear calibration range for Trp in the presence of 10 M AA and 50 M UA was 0.2–150 M, with a correlation coefficient of 0.9996, and a detection limit of 0.06 M. The proposed method was successfully applied for determination Trp, UA and AA in biological systems and pharmaceutical samples

Description Zirconium phosphated amorphous silica gel (devoted briefly as Si–ZrPH) modified carbon paste electrode (CPE) was used for detection of dopamine (DA) in the presence of ascorbic acid (AA) and uric acid (UA). Cyclic voltammetry demonstrated improved reversibility of the DA on the modified electrode. Cyclic voltammetry of Fe(CN)6 3−/4− as a negatively charged probe revealed that the surface of the Si–ZrPH modified CPE surface had a high density of negative charge. As a result, the modified carbon paste electrode could inhibit the voltammetric response of AA and UA while the redox reaction of dopamine was promoted. Based on this, a selective method has been developed to detect DA in the presence of 2500 and 1000 time higher concentration of AA and UA, respectively. The effect of various experimental parameters on the voltammetric response of dopamine was investigated. Under the chosen conditions, the differential pulse voltammetry peak current was found to be linear with DA concentration in the ranges of 0.04 to 50 µM and 50 to 400 µM. The detection limit of the proposed method in the presence of 100 µM of AA and 40 µM of UA was found to be 0.02 µM for DA determination. Satisfying results are achieved when detecting the DA in injection and human serum samples.

Description A chemically modifed electrode was constructed based on a multi-walled carbon nanotubemodifed glassy carbon electrode (MWCNTs/GCE). It was demonstrated that this sensor can be used for the simultaneous determination of the pharmaceutically important compounds paracetamol (PAR) and tramadol (TRA). The measurements were carried out by the application of differential pulse voltammetry (DPV), cyclic voltammetry (CV) and chronoamperometry (CA) methods. Application of the DPV method demonstrated that in phosphate buffer (pH 7.5) there was a linear relationship between the oxidation peak current and the concentration of PAR over the range 0.5 μmol L-1 to 210 μmol L-1. A similar linear correlation between oxidation peak current and concentration was observed for TRA over the range of 2 μmol L-1to 300 μmol L-1. Under optimal conditions the modifed electrode exhibited high sensitivity, selectivity and stability for both PAR and TRA determination, making it a suitable sensor for the simultaneous submicromolar detection of PAR and TRA in solutions. The analytical performance of this sensor has been evaluated for detection of PAR and TRA in human serum, human urine and some pharmaceutical preparations with satisfactory results.

Description The redox response of a modified carbon nanotube paste electrode of ferrocenemonocarboxylic acid (FMC) was investigated. Differential pulse voltammetric peak currents of norepinephrine (NE) increased linearly with its concentrations at the range of 0.52 μM to 530 μM and the detection limit (3σ) was determined to be 0.16 μM. The diffusion coefficient (D) and transfer coefficient (α) of NE were also determined. Mixture of NE and folic acid (FA) can be separated from one another by differential pulse voltammetry. These conditions are sufficient to allow determination of NE and FA both individually and simultaneously

Description A chemically modifed electrode is constructed based on multi-walled carbon nanotube modifed glassy carbon electrode (MWCNTs/GCE). It was demonstrated that this sensor could be easily used for determination of acetaminophen (ACT) in aqueous buffered media. The measurements were carried out by application of differential pulse voltammetry (DPV), cyclic voltammetry (CV) and chronoamperometry (CA) methods. Application of DPV method showed two linear dynamic ranges. The frst linear dynamic range was from 0.1 to 22 μmol L-1, with a calibration equation of Ip(μA) = 1.2782c (mmol L-1) + 0.2431 (R2 = 0.9984) and the second linear dynamic range was between 26 to 340 μmol L-1 with a calibration equation of Ip(μA) = 0.7793c (mmol L-1) + 11.615 (R2 = 0.9986). A detection limit of 0.029 μmol L-1 (S/N = 3) was obtained. The modifed electrode showed electrochemical responses with high sensitivity, excellent selectivity and stability for ACT determination at optimal conditions, which makes it a suitable sensor for submicromolar detection of ACT in solutions. The analytical performance of this sensor has been evaluated for detection of ACT in human serum, human urine and a pharmaceutical preparation with satisfactory results.

Description A chemically modified electrode is constructed based on a multi-walled carbon nano-tubes (MWNTs) and nickel hydroxide nano-particles (NHNPs) composite modified-glassy carbon electrode (MWNTs/NHNPs/GCE). It is demonstrated that this sensor can be used for the simultaneous determination of ascorbic acid (AA), dopamine (DA) and uric acid (UA). The measurements were carried out by the application of differential pulse voltammetry (DPV), cyclic voltammetry (CV) and chronoamperometry (CA) methods. Application of the DPV method demonstrated that in phosphate buffer (pH = 6) there was a linear relationship between the oxidation peak current and the concentration of AA over the range of 7–4500  mol L−1. For DA the linear relationship was in the range of 2–625 mol L−1. A similar linear relationship between oxidation peak current and concentration was observed for UA over the range of 0.8–470 mol L−1. Under optimal conditions the modified electrode exhibited high sensitivity, selectivity and stability for AA, DA and UA determination, making it a suitable sensor for the simultaneous submicromolar detection of AA, DA and UA in solutions. The experimental results suggest that the hybrid film modified electrode combining the advantages of NHNPs and carbon nanotubes which accelerates the electron transfer reaction of AA, DA and UA on the electrode surface. The analytical performance of this sensor has been evaluated for detection of AA, DA and UA in human serum and human urine with satisfactory results.

Description A novel myoglobin-based electrochemical biosensor was developed. The fabricated biosensor is based on a nanobiocomposite prepared from multiwalled carbon nanotubes and Ni(OH)2 nanoparticles that were coated with myoglobin and chitosan. Cyclic voltammogram of the electrode showed a pair of well-defined and quasi-reversible redox peaks with a formal potential (E0') of –0.330 V in 0.1 M pH=7.5 phosphate buffer solution, which was the characteristic of the Mb heme Fe(III)/Fe(II) redox couple. Immobilized Mb exhibits excellent electrocatalytic activity toward the reduction of hydrogen peroxide. The linear range for the determination of hydrogen peroxide was from 0.4 to 702 µM with a detection limit of 0.08 µM using chronoamperometry method. The kinetic parameters such as the electron transfer coefficient and the heterogeneous electron transfer rate constant for H2O2 determination were determined using electrochemical approaches. The biosensor was used for determination of H2O2 in human blood serum and the oxidant with satisfactory results

Description The electrochemical oxidation of dopamine (DA) and serotonin (ST) have been investigated by application of Nafion/Ni(OH)2-multiwalled carbon nanotubes modified glassy carbon electrode (Nafion/Ni(OH)2-MWNTs/GCE) using cyclic voltammetry (CV), differential pulse voltammetry (DPV) and chronoamperometry (CA) methods. The modified electrode worked as an efficient electron-mediator for DA and ST in the presence of ascorbic acid (AA). Voltammetric techniques separated the anodic peaks of DA and ST, and the interference from AA was effectively excluded from DA and ST determination. The DPV data showed that the obtained anodic peak currents were linearly proportional to concentration in the range of 0.05–25 mol L−1 with a detection limit (S/N = 3.0) of 0.015 mol L−1 for DA and in the range of 0.008–10 mol L−1 and with a detection limit of 0.003 mol L−1 for ST. The proposed sensor was used for determination of ST and DA in human blood serum with satisfactory results.

Description A novel modified carbon ionic liquid electrode is prepared as an electrochemical sensor for simultaneous determination of levodopa (l-dopa) and serotonin (5-HT). The experimental results suggest that a carbon ionic liquid electrode modified with multi-walled carbon nanotubes and cobalt hydroxide nanoparticles, and coated with Nafion (Nafion/Co(OH)2–MWCNTs /CILE), accelerates the electron transfer reactions of l-dopa and 5-HT. In addition it shows no significant interferences of uric acid and ascorbic acid as electroactive coexistent compounds with l-dopa and 5-HT in biological systems. The fabricated sensor revealed some advantages such as convenient preparation, good stability and high sensitivity toward 5- HT and l-dopa determination. The DPV data showed that the obtained anodic peak currents were linearly dependent on the l-dopa and 5-HT concentrations in the range of 0.25–225 and 0.05–75 mol L−1, respectively. The applicability of the modified electrode was demonstrated by simultaneous determination of 5-HT and l-dopa in human serum

Description A novel modified carbon ionic liquid electrode (CILE) is prepared as an electrochemical sensor for simultaneous determination of levodopa (l-Dopa) and melatonin (Mel). The experimental results suggest that a carbon ionic liquid electrode modified with multi-walled carbon nanotubes and cobalt hydroxide nanoparticles accelerates the electron transfer reactions of l-Dopa and Mel. The fabricated sensor revealed some advantages such as convenient preparation, good stability and high sensitivity. The DPV data in 0.1 M phosphate buffer solution (PBS) (pH 7.5) allowed a method to be developed for the determination of l-Dopa and Mel concentrations in the ranges 0.1–300 and 0.01–50 M, with the detection limits of 0.075 and 0.004 M, respectively. The proposed method was successfully applied to determinations of these compounds in some pharmaceutical and human urine samples.
