RESUMEN
The extensive use of chemical pesticides has significantly boosted agricultural food crop yields. Nevertheless, their excessive and unregulated application has resulted in food contamination and pollution in environmental, aquatic, and agricultural ecosystems. Consequently, the on-site monitoring of pesticide residues in agricultural practices is paramount to safeguard global food and conservational safety. Traditional pesticide detection methods are cumbersome and ill-suited for on-site pesticide finding. The systematic review provides an in-depth analysis of the current status and perspectives of nanobiosensors (NBS) for pesticide detection in the agricultural arena. Furthermore, the study encompasses the fundamental principles of NBS, the various transduction mechanisms employed, and their incorporation into on-site detection platforms. Conversely, the assortment of transduction mechanisms, including optical, electrochemical, and piezoelectric tactics, is deliberated in detail, emphasizing its advantages and limitations in pesticide perception. Incorporating NBS into on-site detection platforms confirms a vital feature of their pertinence. The evaluation reflects the integration of NBS into lab-on-a-chip systems, handheld devices, and wireless sensor networks, permitting real-time monitoring and data-driven decision-making in agronomic settings. The potential for robotics and automation in pesticide detection is also scrutinized, highlighting their role in improving competence and accuracy. Finally, this systematic review provides a complete understanding of the current landscape of NBS for on-site pesticide sensing. Consequently, we anticipate that this review offers valuable insights that could form the foundation for creating innovative NBS applicable in various fields such as materials science, nanoscience, food technology and environmental science.

Oxidative stress, imbalanced antioxidants, and dysregulated renal lipids are closely linked with diabetic nephropathy and eventual cause of end-stage renal failure. This study was performed to investigate the protective effect of bacoside-A on markers of lipid peroxidation, renal lipids, and markers of renal function in diabetic rats. Experimental diabetes was induced in Wistar rats by a single dose of streptozotocin [40 mg/kg body weight (BW)] via intraperitoneal injection. Oral administration of bacoside-A (10 mg/kg BW) and glibenclamide, a reference drug, continued for 45 days. Diabetic rats showed a significant increase in the levels of plasma glucose, renal lipids, markers of renal lipid peroxidation, and plasma biomarkers of renal function such as urea, uric acid, and creatinine. A significant decrease in the levels of plasma insulin, nonenzymatic antioxidants, and the activity of enzymatic antioxidants was seen compared with the normal controls. Bacoside-A (10 mg/kg BW) and glibenclamide (600 µg/kg BW) administered to diabetic rats resulted in a significant decrease in plasma glucose and renal lipids but a significant increase in the plasma insulin level. In addition, bacoside-A achieved a remarkable increase in the activity of enzymatic antioxidants and the levels of nonenzymatic antioxidants in the renal tissue of diabetic rats, along with significant decreases in the markers of lipid peroxidation and those of renal function, consequently substantiating the protecting effectiveness of bacoside-A in a diabetic state. These biochemical observations were supported by a histopathological study of the renal tissue. The present study suggested that bacoside-A, a triterpenoid, offers a higher renoprotective effect to counter abnormal parameters of renal function in diabetes-induced renal injury.
