    ABSTRACT: Electrochemical telomerase assay (ECTA) developed by our group was evaluated in an oral cancer screening using exfoliated oral cells and tissues obtained from patients of oral cancer, mucosa associated disease, or healthy volunteers. Telomerase activity from ECTA is correlated with hTERT mRNA expression level using a real-time PCR and was increasing in the following order: healthy volunteer group<mucosa associated disease group<oral cancer group. Sensitivity and specificity of ECTA were 88 % and 72 %, respectively when used 17 % of the threshold value based on the receiver operating characteristic curve in ECTA data.

    ABSTRACT: Graphene nanosheets (GS) were prepared through solvent exfoliation, and used to greatly enhance the oxidation activity of rutin. On the surface of GS, a sensitive oxidation wave at 0.26 V was observed for rutin, and the peak currents increased significantly. As a result, a highly sensitive electrochemical method was developed for the determination of rutin. The linear range was from 10 nM to 1.25 μM, and the detection limit was 3.2 nM. It was used in the analysis of traditional Chinese medicines, and the results consisted with the values of that obtained by high performance liquid chromatography.

    ABSTRACT: A modified glassy carbon electrode with a film of nano diamondgraphite nano mixture decorated with Ag nanoparticles (AgNPsNDG/GCE) was constructed and used for sensitive voltammetric determination of ceftizoxime (CFX). Morphology of AgNPsNDG/GCE has been examined by scanning electron microscopy (SEM) and atomic force microscopy (AFM). Experimental variables such as deposited amount of the modifier suspension, pH of the supporting electrolyte and accumulation potential and time were optimized by monitoring of CV and LSV responses of CFX. The results illustrate that AgNPsNDG/GCE exhibits an excellent electrocatalytic effect in the electro-oxidation of CFX that leads to a considerable improvement in the corresponding anodic peak current. This also allows the development of a highly sensitive voltammetric sensor for the determination of CFX in pharmaceutical and clinical samples. Under the optimum conditions, the modified electrode showed a linear response to the concentration of CFX in the range of 0.02–7 µM with detection limit of 6 nM. The prepared modified electrode has some remarkable electrochemical properties such as simple preparation, high sensitivity, excellent repeatability and reproducibility and long-term stability.

    ABSTRACT: New procedures for the determination of pesticide carboxin were developed using differential pulse voltammetry, HPLC with amperometric detection and chronopotentiometry at carbon paste electrode and reticulated vitreous carbon electrode, respectively. Developed procedures based on electrochemical oxidation of carboxin were successfully applied on the determination of carboxin in the model samples of drinking and river water. Limits of detection in samples of river water were in 10−7 mol L−1 concentration range for all procedures and electrodes used. All developed procedures proved to be sensitive, accurate and, due to the resistance of the electrode to the passivation, also simple to handle.

    ABSTRACT: In this paper, bisphenol A was determined by electrochemical method at a nitrogen-doped carbon nanofiber modified carbon paste electrode (NCNF/CPE) with high sensitivity and good selectivity. NCNF was obtained by a simple electrospinning followed by carbonization procedure, in which polyacrylonitrile (PAN) as precursor and nitrogen doping was realized by re-utilizing the tail gas that produced in the thermal pretreatment process. Good reproducibility and high stability were obtained for BPA detection at NCNF modified CPE. Current response plotted with BPA concentration was linear in the range of 0.1–60 μM with LOD of 0.05 μM. The proposed electrochemical sensor was employed for BPA determination with satisfactory recoveries for real water samples, indicating the practical applicability of NCNF/CPE.

    ABSTRACT: The present work describes the fabrication of paper-based analytical devices (μPADs) by immobilization of glucose oxidase onto the screen printed carbon electrodes (SPCEs) for the electrochemical glucose detection. The sensitivity towards glucose was improved by using a SPCE prepared from homemade carbon ink mixed with cellulose acetate. In addition, 4-aminophenylboronic acid (4-APBA) was used as a redox mediator giving a lower detection potential for improvement selectivity. Under optimized condition, the detection limit was 0.86 mM. The proposed device was applied in real samples. This μPAD has many advantages including low sample consumption, rapid analysis method, and low device cost.

    ABSTRACT: Graphene nanosheets (GS) were prepared via ultrasonic exfoliation, and used to modify glass carbon electrode (GCE). Compared with GCE, the GS-modified GCE (GS/GCE) greatly increased the anodic stripping peak currents of Cd2+ and Pb2+. Moreover, the response signals of Cd2+ and Pb2+ on GS/GCE further enhanced remarkably in the presence of Bi3+. Based on the synergistic enhancement effects of GS and Bi3+, a novel electrochemical sensor was developed for Cd2+ and Pb2+. The detection limits were 0.35 and 0.045 μg L−1 for Cd2+ and Pb2+. It was used in food sample analysis, and the accuracy was tested by ICP-MS.

    ABSTRACT: The anodic electrochemiluminescence (ECL) of dissolved oxygen with 2-(dibutylamino) ethanol (DBAE) on platinum electrode has been reported previously by our group. Interestingly, the ECL intensity can be greatly amplified at TiO2 nanoparticles modified platinum electrode (TiO2/Pt), which is due to the catalytic effect of TiO2 nanoparticles to electrochemical oxidation of DBAE. It is the first case to obtain the enhanced ECL from luminophor by electrochemical catalysis of co-reactant. The enhanced anodic ECL intensity can be quenched by dopamine sensitively. And the ECL intensity versus the logarithm of concentration of dopamine was linear over the 4.0×10−12–1.8×10−8 M (R2=0.9957), with the limit of detection of 2.7×10−12 M (S/N=3).

    ABSTRACT: The development of therapeutic compounds that can attenuate the toxicity exerted by the accumulation of metal ions has been an area of intensive research in neurodegenerative diseases. In this report, an electrochemical method was developed to determine the Cu(II)-chelating ability of polyphenols that were implicated in Alzheimer’s disease (AD). The results suggested the strength of flavonoids to chelate Cu(II) as epigallocatechin-3-gallate (EGCG)>resveratrol>clioquinol>baicalein∼scyllo-inositol. Furthermore, the number of hydroxyl groups was found to play a role to lower Cu(II) oxidation signal using differential pulse voltammetry.

    ABSTRACT: Electrochemistry is one of the most advanced techniques for monitoring neurochemical activities in the living brain because electrochemical approaches bear the advantageous features of high spatial and temporal resolutions, which facilitate its tremendous potential in investigating the highly spatially heterogeneous brain system and the fast dynamics of neurochemical activities. On the other hand, since brain is the most complicated organ in the sense of its numerous kinds of neurochemical species, high selectivity is always required for any analytical methods that approach the brain. In this review, we will discuss various electrochemical methodologies to achieve selective detection of neurochemicals in mammalian brain and the strategies developed mainly by our group towards selective monitoring of both electrochemically active and inactive neurochemicals. At the end, we will discuss possible solutions towards brain mapping of neurochemical species and combination of neurochemical detection strategy with electrophysiology as the direction of future development of electroanalysis in living brain.

    ABSTRACT: Fast and sensitive method of prednisolone determination at renewable mercury film electrode using differential pulse adsorptive stripping voltammetry (DPAdSV) was successfully developed. The effects of various factors such as: preconcentration potential and time, pulse height, step potential and supporting electrolyte composition were optimized. A linear voltammetric response for analyte was obtained in the concentration range from 0.05 µmol L−1 (18 µg L−1) to 2.25 µmol L−1 (0.81 mg L−1), with a detection limit of 0.01 µmol L−1 for preconcentration time of 20 s. Repeatability of method was determined as RSD % for prednisolone concentration of 0.04 µmol L−1 as 1.6 % (n=9). The proposed method was successfully applied and validated by recovery parameter of prednisolone in simulated sample and pharmaceutical product.

    ABSTRACT: The electrode kinetics of vitamin B2 was measured at a constant scan rate of a square-wave (SW) voltammetric experiment by recently introduced method based on alteration of the height (amplitude) of the SW potential pulses. The electrode reaction mechanism was analyzed in the light of the simplified model considering two-electron one step surface electrode mechanism, as well as to more appropriate EE surface reaction pathway consisting of two successive one-electron quasireversible reactions. Theoretical analysis indicated that the evolution of the voltammetric response under variation of the SW amplitude enables estimation of the rate determining step of the EE mechanism.

    ABSTRACT: A sensitive electrochemical method based on square wave cathodic adsorptive stripping voltammetry (SWCASV) using pencil graphite electrodes (PGE) was developed for the individual and simultaneous determination of the anticancer drugs flutamide (Flu) and irinotecan (Irino) in biological fluids. Calibration curves showed an excellent linear response with limits of detection of 1.68×10−9 and 1.55×10−8 M Irino and Flu, respectively. The statistical evaluation of within-day repeatability (n=5) and day to day precision (n=5) showed satisfactory accuracy and precision. SWCASV using a PGE for individual and simultaneous determination of both drugs in bulk form, human urine and serum samples was demonstrated.

    ABSTRACT: A non-invasive device based on measurements of electrochemical skin conductance can detect small fiber neuropathy, a sweat gland dysfunction implicated in several diseases. The measurement is related to sweat composition and notably to chloride concentration. To optimize the electrode material, in vitro experiments are performed in mimetic sweat solutions. This work reports on the resistance to pitting corrosion of biocompatible stainless steels (AISI 304L, AISI 430, AISI 430T, D2205) in sweat mimicking electrolyte at pH 7 with variable chloride concentration, to determine the most sensitive material to sweat composition. AISI 430 is promising due to its high sensitivity to chloride concentration variations.

    ABSTRACT: A carbon screen-printed electrode modified in-situ with lead film (PbF-SPCE) was applied for the adsorptive stripping voltammetric determination of Co(II) in the form of a complex with 1,2-cyclohexanedione dioxime. Lead film was electrochemically deposited in situ on SPCE from a 0.2 M ammonia buffer solution (pH 8.7) containing 5 ⋅ 10−5 M Pb(NO3)2 and 5 ⋅ 10−5 M nioxime. Due to the very low LOD (0.003 µgL−1, i.e., 0.05 nmol L−1 Co(II); tacc=120s), the developed procedure could be rated among the most sensitive methods employing SPEs. The Ni(II) signal was significantly lower than the Co(II) one and the separation of Ni(II) and Co(II) peaks was even better at the PbF-SPCE than at the hanging mercury drop electrode.

    ABSTRACT: A voltammetric sensor for determination of paracetamol in the presence of morphine is described for the first time. The synthesized CdO nanoparticles were characterized with different methods such as scanning electron microscopy (SEM) and X-ray diffraction (XRD). The paracetamol and morphine peaks are separated ca. 0.37 and 0.65 V, respectively; hence paracetamol can be analysed in the presence of morphine and more than 21 times of the current excess of paracetamol. The detection limits for paracetamol and morphine were 0.07 and 0.1 μM, respectively. The sensor has been successfully applied for the assay of the above compounds in real samples.

    ABSTRACT: This article highlights the potential use of multi-walled carbon-nanotube modified screen-printed electrodes (SPEs) for the amperometric sensing of ciprofloxacin and compares the association of batch-injection analysis (BIA) and flow-injection analysis (FIA) with amperometric detection. Both analytical systems provided precise (RSD<5 %) and sensitive determination of ciprofloxacin (LOD<0.1 μmol L−1) within wide linear range (up to 200 μmol L−1). Accuracy of both methods was attested by recovery values (93–107 %) and comparison with capillary electrophoresis. The BIA system is completely portable (especially due to association with SPEs) and provided faster analyses (130 h−1) and more sensitive detection than the FIA system due to the higher flow rates of injection.

    ABSTRACT: Calretinin (CAL) is calcium binding protein, and its levels in blood and cerebrospinal fluids are increased, since its expression is increased various cancer types. A novel biosensor system fabricated by immobilization of a specific antibody to CAL, anti-Calretinin (anti-CAL), onto a gold electrode surface via an effective covalent binding method using mercaptohexanol, epichlorohydrin, and ethanolamine was reported for the sensitive, selective, and accurate analysis of CAL. The proposed biosensor showed a linear calibration range between 1 ng/mL and 5 ng/mL. LOD and LOQ values were determined as 0.11 ng/mL and 0.38 ng/mL, respectively. The standard deviation related to the reproducibility of the new biosensor system was calculated as 3.95 %. Lastly, in order to state the applicability of the biosensor to early diagnosis of CAL in practice, artificial serum samples spiked with CAL have been analyzed by the proposed biosensor.
