A magnetic molecularly imprinted electrochemical sensor was developed for selective determination of sufentanil (SUF) based on carbon paste electrode (CPE) modified with methacrylic acid-ethylene glycol dimethacrylate-coated Fe3O4 nanoparticles (Fe3O4@MAA-EGDMA NPs). The structural properties, chemical structure, and electrochemical behaviors of the imprinted sensor were characterized by X-ray diffraction analysis (XRD), Fourier transform infrared spectroscopy (FT-IR), and square wave voltammetry (SWV), respectively.

A simple and environment-friendly electrochemical method using activated glassy carbon electrodes (aGCE) for monitoring the residues of tetracycline in pork samples was developed. A two-step pretreatment procedure was established for activating the glassy carbon electrode surface, including mechanical polishing and electrochemical pretreatment. In the supporting electrolyte solution of 0.2 M sodium sulfate (at pH 2.5), the electrochemical response of TC was characterized by two irreversible oxidation peaks at +0.95 V and +1.05 V vs. saturated calomel electrode.

A facile hydrothermal-aided process is demonstrated to prepare an analcime 3-dimensional (3D) network using recycled aluminum foil as an aluminum source without using an organic template. The prepared material was characterized by different techniques. An electrode/electrolyte interface with a 3D network structure allows for better contact and improves the kinetics of the charge transfer.

The main objective of this study is the development of surface-printed carbon electrodes (SPCE) modified with folic acid imprinted nanostructures (FA-Imp-poly(MPTS-rGO-co-NAT), which will be used for the first time for folic acid determination in commercially human blood serum. For this purpose, the synthesis of nanostructures has been carried out and characterized by FTIR, SEM-EDS, and AFM. Then, a new chemically modified nanosensor was fabricated for the determination of folic acid using folic acid imprinted nanostructures.

In particular, those materials present the highest amount of meso (3–10 nm) and larger meso-macropores and the highest content of fluorine in their composition. Then, fluorine-doped silicon oxycarbide derived materials can be potentially used as electrodes for supercapacitors in the field of energy storage applications.

A simple approach to constructing a double-layer voltammetric sensor is described. The poly(malachite green) (PMG) and multiwalled carbon nanotubes (MWCNTs) were coimmobilized at the surface of the glassy carbon electrode (GCE) for fabrication of PMG/MWCNT/GCE. The modified electrode was characterized by cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), differential pulse voltammetry (DPV), and chronoamperometric techniques.

Thiolated chitosan (CS–TGA) was prepared using chitosan (CS) and thioglycolic acid (TGA). Then MWCNTs were added to the mixture of CS–TGA and CS to prepare the CS/CS–TGA/MWCNs porous composite by freeze-drying method and this composite was used to modify an indium tin oxide glass electrode. The electrode was used as a sensor for Pb2+. The morphology and structure of the composite were characterized by infrared spectroscopy and scanning electron microscope, and their electrochemical behavior was also studied.
