A screen-printed electrochemical sensor based on Fe3O4@cellulose nanocrystals/Cu nanocomposite (Fe3O4@CNC/Cu) has been constructed for the sensitive detection of venlafaxine. The magnetic Fe3O4@cellulose nanocrystal/Cu nanocomposite was prepared by a green procedure using a plant extract (Petasites hybridus leaf) as a stabilizing and reducing agent for copper. The formation of Fe3O4@CNC/Cu was validated through X-ray diffraction, Fourier transform infrared spectroscopy, transmission electron microscopy, field emission scanning electron microscopy, energy-dispersive X-ray spectroscopy, ultraviolet–visible spectral analysis, vibrating sample magnetometer, and thermal analysis. Fe3O4@CNC/Cu was next used for modifying a graphite screen-printed electrode, intended for the analysis of venlafaxine concentration. The electrochemical behavior of venlafaxine on the resulting electrode was evaluated through cyclic and differential pulse voltammetry and chronoamperometry. The tests indicated that the sensor has good performance for the electrochemical detection of venlafaxine. Under optimized conditions, the linear dynamic range for venlafaxine concentrations by the modified electrode was 0.05–600.0 μM, and the limit of detection was 0.01 μM. In addition, the developed technique was also demonstrated as a selective, easy, and precise sensor to identify venlafaxine in urine, water, and pharmaceutical formulation samples.

“…Moreover, the findings obtained from DPV exhibited greater sensitivity in detecting VEN in 1.0-500.0 µM with LOD equal to 0.5 µM (S/N = 3). Finally, this disposable sensor showed a satisfactory utilization in the drug formulations, water, and urine samples [13]. The other study by Maddah et al devised one of the sensitive electrochemical SPEs modified with the La 3+ /Co3O4 nanocubes for VEN determination, demonstrating higher validity [13].…”

Venlafaxine (VEN), as one of the popular anti-depressants, is widely utilized for the treatment of major depressive disorder, panic disorder, as well as anxiety. This drug influences the chemicals in the brain, which may result in imbalance in depressed individuals. However, venlafaxine and its metabolites are contaminants in water. They have exerted an adverse influence on living organisms through their migration and transformation in various forms of adsorption, photolysis, hydrolysis, and biodegradation followed by the formation of various active compounds in the environment. Hence, it is crucial to determine VEN with low concentrations in high sensitivity, specificity, and reproducibility. Some analytical techniques have been practically designed to quantify VEN. However, electroanalytical procedures have been of interest due to the superior advantages in comparison to conventional techniques, because such methods feature rapidity, simplicity, sensitivity, and affordability. Therefore, this mini-review aims to present the electrochemical determination of VEN with diverse electrodes, such as carbon paste electrodes, glassy carbon electrodes, mercury-based electrodes, screen-printed electrodes, pencil graphite electrodes, and ion-selective electrodes.
