Nanoarchitectonics of europium vanadate nanoparticles decorated carbon nanofibers for electrochemical detection of fungicide in fruits

Background

Fungicides, like carbendazim, have effects on male fertility. There have been sufficient studies conducted on certain chemical compounds to indicate a selective action at the epididymis level. To prevent contamination of food products with fungicides, most of the governments have established rules for the use of fungicides. However, even though this type of fungicide is primarily used in agriculture. More probably, it's contaminated with fruits and vegetables. In particular, carbendazim is one of the major fungicides in the agricultural usage

Methods

This research work developed a europium vanadate (EuVO₄) nanoparticle decorated carbon nanofiber (CNF) composites by hydrothermal-sonochemical approach. Based on this composite, Carbendazim sensing is developed through electrochemical oxidation based on EuVO₄/f-CNF modified Glassy Carbon Electrode (GCE). By combining EuVO₄ and f-CNF with the GCE, carbendazim detection can be highly effective. GCEs are rigid, making them ideal for depositing EuVO₄/f-CNF, while their expansive surface area makes it possible to immobilize a greater amount of EuVO₄/f-CNF, which could increase the Carbendazim sensing ability of the resulting modified GCEs with EuVO4/f-CNF.

Main Findings

: The carbendazim sensing was actualized by the electrocatalytic oxidation of carbendazim on the composite modified electrode, and it is demonstrating a linear range of 0.125 to 23.875 – 33.81 to 131.375 µM with a remarkably limit of detection of 0.00612 µM. The EuVO₄/f-CNF /GCE also showcased an excellent degree of stability, retaining 96.5 % of its initial activity even after 30 days. This research highlights the potential of EuVO₄/f-CNF modified GCEs as robust, and efficient platform for the carbendazim detection under electrochemical approach.
