Electrochemical investigation of zinc tungstate nanoparticles; a robust sensor platform for the selective detection of furazolidone in biological samples

Abstract

Alacritous determination, linear dynamic range, quick response time, and selectivity are the pivotal indices for developing electrochemical sensors. The researchers in the society are interested in upgrading the electroanalytical performance of electroactive materials with its chemical components and structures. Therefore, we have successfully prepared zinc tungstate nanoparticles (ZW NPs) via an ultrasonic-assisted co-precipitation synthesis technique. The as-prepared ZW NPs were cast on the screen-printed carbon electrode surface (SPCE) and utilized as a new electrode material for electrochemical detection of antibiotic drug furazolidone (FUZ). The structural morphology of as-prepared ZW NPs was analyzed with the assistance of FE-SEM, HR-TEM, and purity of nanomaterial formation were characterized by PXRD, Raman, and XPS. The electrochemical experiments were carried out using CV and DPV techniques. The ZW NPs/SPCE electrocatalyst shows an excellent sensing performance towards the determination of FUZ with a wide linear range from 0.1 to 849 μM, trace LOD, and sensitivity was assessed to be 13 nM and 0.77 µA µM−1 cm−2 respectively. This article marvels at the recent findings of nitrofuran drug detection in biological samples as a resilient and reliable FUZ sensor probe with good selectivity and excellent stability, and it attains cynical importance for surveying the ecosystem.
