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 ...
Development of a New Electrochemical Sensor Based on Mag-MIP Selective Toward Amoxicillin in Different Samples
(2021-03-19)
This work describes an electrochemical sensor for the selective recognition and quantification of amoxicillin and a β-lactam antibiotic in real samples. This sensor consists of a carbon paste electrode (CPE) modified with ...
Simple and highly sensitive 2-hydroxy-1,4-naphthoquinone/glassy carbon sensor for the electrochemical detection of [Ni(CN)4]2− in metallurgical industry wastewater
(2022-01-01)
The pollution generated by the metallurgical industry effluents represents a serious issue for human health and the environment where the presence of cyanide species is particularly dangerous even at low concentration. In ...
Construction of an electrochemical sensing platform based on platinum nanoparticles supported on carbon for tetracycline determination
(2016-06-02)
In this paper, we report the construction of an electrochemical sensing platform based on platinum nanoparticles supported on carbon (PtNPs/C) for the determination of the antibiotic tetracycline (TTC). Initially, the ...
A Polyhedral Oligomeric Silsesquioxane (POSS) Doped with Cerium(III) / Fe(II) and its Application as an Electrochemical Sensor for L-dopamine
(2022-01-01)
A Polyhedral oligomeric silsesquioxane (POSS) doped with cerium (III) was synthesized and reacted with potassium hexacyanoferrate (SCeH). The vibrational, structural, morphological and electrochemical properties of this ...
Improving the Analytical Reproducibility of Electrochemical Capacitive Sensors Using the Chemical Hardness of the Interface
(2021-01-01)
Miranda and Bueno recently demonstrated that chemical hardness could be experimentally measured and used as a chemical reactivity index of electrochemical interfaces. Herein, we applied this reactivity index concept to ...
Applicability of activated carbon obtained from peach stone as an electrochemical sensor for detecting caffeine
(2018-08-01)
Simple, economical and highly sensitive electrodes for the detection of caffeine by using activated carbon from peach stones have been developed. The activated carbons were synthesized by chemical activation using ZnCl2 ...
Ultrahigh-Gain Organic Electrochemical Transistor Chemosensors Based on Self-Curled Nanomembranes
(2021-01-01)
Organic electrochemical transistors (OECTs) are technologically relevant devices presenting high susceptibility to physical stimulus, chemical functionalization, and shape changes—jointly to versatility and low production ...
Combining electrochemically reduced graphene oxide and Layer-by-Layer films of magnetite nanoparticles for carbofuran detection
(Elsevier B.V., 2020-10-01)
Carbofuran (CBF) is a pesticide currently prohibited in many countries. It can cause serious damages in the nervous system and has been associated with cancer. However, CBF residues are still found in food samples around ...
Development of a flexible and disposable electrochemical sensor based on poly (butylene adipate-co-terephthalate) and graphite for hydroquinone sensing
(2022-11-01)
We propose the manufacture and optimization of a flexible electrochemical sensor composed of graphite and the polymer poly (butylene adipate-co-terephthalate) (PBAT). The characterization was performed by cyclic voltammetry ...
