This study describes the fabrication of three-dimensional, open-cell, noble-metal (Au, Ag, and Pt) electrodes that have a complex geometry, i.e., wire mesh, metallic foam, "origami" wire mesh, and helix wire mesh. The electrodes were fabricated using an ultrasonication-assisted electroplating method that deposits a thin, continuous, and defect-free...

Ion transfer at micro-interfaces formed between two immiscible electrolyte solutions (µITIES) is a powerful platform for the detection of charged species. Ametryn is used as a model target analyte to investigate the detection at µITIES of lipophilic and ionisable herbicides derived from triazine. A twostep detection method is proposed, which is tak...

Food spoilage is caused by the development of microorganisms, biogenic amines, and other harmful substances, which, when consumed, can lead to different health problems. Foodborne diseases can be avoided by assessing the safety and freshness of food along the production and supply chains. The routine methods for food analysis usually involve long a...

In this work a Metal–Organic Framework (MOF) was prepared using a solvothermal method, taking as precursors 1. 2-di-(4-pyridyl)-ethylene, 1.2.4.5-benzenetetracarboxylic acid and Co(No3)2-6H2O. This MOF was called UV-11 and was evaluated using microscopic, spectroscopic and electrochemical techniques. According to the obtained results, the melting p...

Heavy metal ions (HMIs) are one of the major environmental pollution problems currently faced. To monitor and control HMIs, rapid and reliable detection is required. Electrochemical analysis is one of the promising methods for on-site detection and monitoring due to high sensitivity, short response time, etc. Recently, nanometal oxides with special...

We demonstrate a novel method for the selective extraction and electrochemical detection of S100β disease biomarker. The protein
is extracted from blood plasma using target-specific gold coated magnetic nanoparticles. This is followed by the rapid reduction of
the disulfide bond structure of the purified protein using chronoamperometry and its immobi...

AbstractIn this paper, the use of a screen printed electrode modified by feather like La3+/ZnO nano-flowers for the determination of sertraline was described. These nano-flowers showed satisfactory catalytic activity for determination of sertraline by cyclic voltammetry (CV) and differential pulse voltammetry (DPV) methods. At the optimum pH of 7.0...

This paper describes the development of a novel, simple, and inexpensive electrochemical device containing an integrated and disposable three-electrode system for detection. The base of this platform consists on a PDMS structure containing microchannels which were prototyped using 3D-printed molds. Pencil graphite leads were inserted into these mic...
