AB  - In present work we report application of bismuth (III) oxide (Bi2O3) decorated graphene nanoribbons (GNR) composite for modification of screen printed electrode, and use of resulting modified screen-printed electrode (SPCE/GNR/Bi2O3) as a disposable glucose biosensor. The composite was synthesized by use of co-precipitation method followed by ultra-sonication. After characterization, the material was applied on the surface of the screen-printed electrode in a ‘drop casting’ fashion. Glucose oxidase (GOx) was added to the modified surface and finally covered by Nafion film. Resulting biosensor electrode (SPCE/GNR/Bi2O3/GOx/Naf) shows excellent performance toward glucose detection, with working linear range from 0.28 to 1.70 mM and detection limit of 0.07 mM. Prepared biosensor was applied for the estimation of glucose level in standard honey samples with declared glucose level, in order to validate the methods (PT scheme). Obtained results are indicating excellent stability, reproducibility, accuracy and precision of the method for the determination of glucose in such samples with negligible matrix effect. Developed biosensor showed high precision, accuracy and selectivity even when employed for determination of glucose content in blood serum and urine samples. Proposed biosensor construction shows promising results and can be considered as stabile and reproducible tool for detection and quantification of glucose in investigated samples. © 2019 Elsevier B.V.

AB  - In this work, we aimed to propose a newly synthesized composite material with enhanced electrocatalytic properties as a novel screen-printed sensor for the quantification of NADH. Additionally, the surface was modified with alcohol dehydrogenase for the preparation of an amperometric biosensor for analysis of ethanol. Synthesized material was characterized using several microstructural (FE-SEM, HR-TEM, XRD) and electrochemical (CV, EIS) techniques. The electrochemical response of the tested analytes was investigated as a function of important parameters. Under optimal conditions, the working linear range and limit of detection for ethanol sensing was 1–1800 µM and 0.19 µM, respectively. For NADH, the linear range was from 1 to 1300 µM with limit of detection of 0.52 µM. Moreover, effects of some possible interfering compounds were investigated and the developed procedure was applied to commercial alcoholic beverages. The results obtained showed satisfactory precision and accuracy of the developed method and confirm the proposed approach could be a possible replacement for the currently used techniques for ethanol and NADH quantification.

AB  - Ergosterol (Erg) is the major sterol component in the plasma membranes of fungi. The main goal of this work was to develop rapid, reliable, and cost-effective method toward Erg detection based on application of unmodified boron-doped diamond electrode. Several organic solvents were tested (acetonitrile, dimethyformamide, dimethylsulfoxide, dichloromethane), and it was found that best analytical characteristics were achieved using acetonitrile containing 0.1 M tetrabutylammonium hexa-fluorophosphate as supporting electrolyte. Oval shaped and well-defined oxidation peak was recorded at potential of around 1.17 V versus Ag/Ag+ non-aqueous reference electrode. Under optimized experimental conditions, linear working range from 2 to 200 mu M was estimated, with limit of detection of 0.7 mu M, using square wave voltammetry. Negligible effect of possible interfering compound was observed. Proposed methodology was successfully applied for estimation of Erg content in mushrooms extract with satisfactory results in comparison with spectrophotometric procedure. Obtained results clearly show that developed analytical methodology can be adequate replacement for the, up to date, used methods and open-novel approach for ergosterol detection.

AB  - A disposable glucose biosensor was prepared using nanoparticles of MnO2 decorated on graphene nanoribbons by surface modification with drop coating with the GOx and Nafion®. Tested material was synthesized and characterized using several techniques. The biosensor could be operated under physiological conditions (0.1 M phosphate buffer, pH 7.4) and exhibited good reproducibility and stability. The linear range for the amperometric response of the biosensor at operating potential of +0.50 (versus Ag/AgCl) was from 0.1 to 1.4 mmol/l, with a detection limit of 0.05 mmol/l and high sensitivity of 56.32 μA/mmol cm2.

AB  - This work present a new approach for the detection of relatively new herbicide pethoxamid (POA), a first electrochemical behavior and determination based on its oxidation on boron-doped diamond electrode in Britton-Robinson buffer solution at pH 4. Square wave voltammetric technique was used for quantification of POA at anodic potential of 1.35 V vs reference Ag/AgCl electrode. The proposed electroanalytical method is operational in the linear working range from 3 to 100 μM of POA with a limit of detection of 1.37 μM. The developed analytical procedure was successfully tested for determination of this herbicide in standard/spiked river water samples and commercial herbicide Successor T SE/spiked river water samples, offering a simple, fast and inexpensive alternative way of pesticide determining to chromatographic methods employed for this purpose.

AB  - In this work, for the first time we proposed electrochemical behavior and development of an analytical procedure for quantification of pesticide clomazone. Electrochemical behavior of clomazone's at boron-doped diamond electrode is characterized with irreversible oxidation at potential of around 1.6 V, in Britton-Robinson buffer solution at pH 2. It was found that potential of this oxidation was not pH dependent excluding presence of proton in the electrochemical reaction. Square wave voltammetry method was the most appropriate for clomazone quantification and proposed procedure was successfully applied for determination of clomazone in river water samples. Obtained parameters, detection limit of 0.21 mu M and working linear range from 1 to 100 mu M and satisfied selectivity can indicate that presented results open new field in research of this group of pesticides and offer possible replacement to the sophisticated and expensive chromatographic methods.

AB  - In this work, the electrochemical behaviour and the subsequent development of an analytical procedure for quantification of pesticide azamethiphos, using boron-doped diamond (BDD) electrode are reported for the first time. It was found that azamethiphos electrochemical behaviour is irreversible oxidation at the potential of around 1.70 V, in 1 M nitric acid (pH 0). Also, it was found that potential of this oxidation was not pH dependent which can be attributed to the no proton involvement in electrochemical reaction on the electrode surface. The square wave voltammetric method was most appropriate for azamethiphos quantification. Under optimised experimental conditions, linear working range from 2 to 100 µM was estimated with the detection limit of 0.45 µM. Negligible effect of the possible interfering compound was observed. The obtained results show that the developed analytical methodology can be an adequate replacement for the, up to date, used methods for detection of organophosphorous pesticide. © 2018, © 2018 Informa UK Limited, trading as Taylor & Francis Group.

abstract = "In this work, the electrochemical behaviour and the subsequent development of an analytical procedure for quantification of pesticide azamethiphos, using boron-doped diamond (BDD) electrode are reported for the first time. It was found that azamethiphos electrochemical behaviour is irreversible oxidation at the potential of around 1.70 V, in 1 M nitric acid (pH 0). Also, it was found that potential of this oxidation was not pH dependent which can be attributed to the no proton involvement in electrochemical reaction on the electrode surface. The square wave voltammetric method was most appropriate for azamethiphos quantification. Under optimised experimental conditions, linear working range from 2 to 100 µM was estimated with the detection limit of 0.45 µM. Negligible effect of the possible interfering compound was observed. The obtained results show that the developed analytical methodology can be an adequate replacement for the, up to date, used methods for detection of organophosphorous pesticide. © 2018, © 2018 Informa UK Limited, trading as Taylor & Francis Group.",
