The routine analysis and detection of organophosphate pesticides (OPPs) in consumer products has become an important activity, due to organophosphate insecticides' extensive applications in agriculture and pest control. We have prepared Gd 2 O 3 hollow nanospheres to fabricate the modified electrode for enzyme-free detection of methyl parathion (MP), one of the most commonly used OPPs. The electrochemical responses of MP on the Gd 2 O 3 hollow nanosphere modified glassy carbon electrode (Gd 2 O 3 /GCE) were investigated in detail. Furthermore, the current of the differential pulse voltammetry (DPV) is linear, with the MP concentration moving from 0.05 μM to 100 μM. It is demonstrated to be a sensitive and simple electrochemical method for the sensing of MP with a low detection limit (0.03 μM). The as-prepared electrode also shows a long-time stability and an acceptable selectivity. The Gd 2 O 3 /GCE is applicable for detecting MP in real samples, such as vegetables, tap water, and paddy field water, with satisfactory results. Therefore, the proposed method is promising for the routine analysis and detection of MP residues in foods and environments.

“…Furthermore, they have distinct inherent optical features like near-infrared photoluminescence and significant resonance Raman scattering. Simultaneously, the electrochemical properties have reactive assemblies installed on the outer surface, which can increase electron transfer [ 88 , 89 ]. Figure 6 shows some silver nanomaterials of different carbon nanotubes (CNT) at different magnifications in thin sheets.…”

Biosensors are a simple, low-cost, and reliable way to detect pesticides in food matrices to ensure consumer food safety. This systematic review lists which nanomaterials, biorecognition materials, transduction methods, pesticides, and foods have recently been studied with biosensors associated with analytical performance. A systematic search was performed in the Scopus (n = 388), Web of Science (n = 790), and Science Direct (n = 181) databases over the period 2016–2021. After checking the eligibility criteria, 57 articles were considered in this study. The most common use of nanomaterials (NMs) in these selected studies is noble metals in isolation, such as gold and silver, with 8.47% and 6.68%, respectively, followed by carbon-based NMs, with 20.34%, and nanohybrids, with 47.45%, which combine two or more NMs, uniting unique properties of each material involved, especially the noble metals. Regarding the types of transducers, the most used were electrochemical, fluorescent, and colorimetric, representing 71.18%, 13.55%, and 8.47%, respectively. The sensitivity of the biosensor is directly connected to the choice of NM and transducer. All biosensors developed in the selected investigations had a limit of detection (LODs) lower than the Codex Alimentarius maximum residue limit and were efficient in detecting pesticides in food. The pesticides malathion, chlorpyrifos, and paraoxon have received the greatest attention for their effects on various food matrices, primarily fruits, vegetables, and their derivatives. Finally, we discuss studies that used biosensor detection systems devices and those that could detect multi-residues in the field as a low-cost and rapid technique, particularly in areas with limited resources.
