Doble role of bathocuproine disulfonic acid as multi-walled carbon nanotubes dispersing agent and copper preconcentration ligand: Analytical applications for the development of hydrogen peroxide and glucose electrochemical sensors
(Elsevier Science, 2020-11)
We are reporting a new strategy for preparing carbon nanotubes (CNTs)-based hydrogen peroxide and glucose amperometric sensors by taking advantage of the dual role of bathocuproine disulfonic acid (BCS) as dispersing agent ...
Recent advances in the development of electrochemical hydrogen peroxide carbon nanotube–based (bio)sensors
(Elsevier, 2019-03)
The relevance of H2O2 as biomarker for different neurodegenerative diseases and cancer has been one of the most significant incentives for the development of new (bio)sensors that allow a more sensitive, selective, fast, ...
Direct determination of monosaccharides in honey by coupling a sensitive new Schiff base Ni complex electrochemical sensor and chemometric tools
(Elsevier Science SA, 2020-06)
The determination and quantification of saccharides is of considerable importance in the food industry among other fields. In this work, we describe for the first time the preparation of the Schiff base Ni complex, ...
Screen-printed electrochemical-based sensor for taxifolin determination in edible peanut oils
(Elsevier Science, 2020-12)
An electrochemical method for the determination of Taxifolin (Tx) in peanut oil samples using screen-printed electrodes (SPEs) is reported for the first time. The different electroanalytical parameters such as scan rate, ...
Electrochemically reduced graphene oxide-based screen-printed electrodes for total tetracycline determination by adsorptive transfer stripping differential pulse voltammetry
(Molecular Diversity Preservation International, 2019-12)
Disposable electrochemically reduced graphene oxide-based (ERGO) screen-printed electrodes (SPE) were developed for the determination of total tetracyclines as a sample screening approach. To this end, a selective ...
Electrochemical sensor for alkaline phosphatase as biomarker for clinical and in vitro applications
(Elsevier Science SA, 2019-02)
Alkaline phosphatase (ALP) is an important biomarker of bone diseases clinically measured in blood as a routine assay by means of optical read-outs, which when compared with electroanalytical methods present lack of ...
Disposable Electrochemical Sensor for Rapid Determination of Ethyl Xanthate in the Mining Industry
(Wiley VCH Verlag, 2018-11)
Xanthate is a widely used reagent in sulfide mineral flotation. A simple and reliable method is presented for the direct monitoring of xanthate in flotation baths and their effluents, as a tool for their reconditioning, ...
Morphological and Chemical Analysis of the Molecularly-Imprinted Polymer-Based D-Arabinose Sensor on a Modified Electrode with Functionalized Carbon Nanotubes
(MDPI, 2019-12)
he sensors modified carbon nanotubes and molecularly imprinted polymers are an excellent choice for the determination of D-arabinose, because they have high selectivity and sensitivity for analysis. This allows the control ...
Modeling the electrochemical response of mesoporous materials toward its application to biomolecular detection
(Wiley VCH Verlag, 2010-06)
The performance of an electrochemical sensor based on the ability of a probe to cross a mesoporous membrane partially blocked by an analyte is predicted using a numerical model. The system comprehends a membrane placed ...
An interesting strategy devoted to fabrication of a novel and high-performance amperometric sodium dithionite sensor
(Elsevier Science, 2019-01)
According to the recently rumors about abusing of sodium dithionite (SDT) in baking bread bysome bakers, we motivated to plan a study to fabricate an electrochemical SDT sensor. Thiswork reports our results on fabricating ...
