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.

Electrochemical determination of salbutamol in aqueous solutions with UiO-66/rGO-modified electrodes
The synthesis of the UiO-66/rGO material involved combining UiO-66 with reduced graphene oxide (rGO). This resulting composite found application in the electrochemical determination of salbutamol (SAL) through modification of a glassy-carbon electrode (GCE) with UiO-66/rGO. Differential pulse voltammetry served as the chosen technique, offering a wide linear range spanning 1–160 μM and demonstrating a low limit of detection at 0.84 μM

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.
