摘要

Nanoparticles have gained prominence in the formulation of nanopesticides, leveraging their unique nanocharacteristics. This study delves into the nephrotoxic implications of CuONanoSheet (CuONS), as nanopesticide tailored for agricultural applications to understand its safety and viability in this field. The nanocharacterization of CuONS was meticulously examined using X-ray diffraction, high-resolution transmission electron microscopy, field emission scanning electron microscopy and Zeta-Sizer device, which assessed zeta-potential, hydrodynamic size, and polydispersity index. Rats treated with CuONS showed elevated levels of blood urea nitrogen, creatinine, and uric acid and a significant increase in lipid peroxidation (MDA) and reduced levels of antioxidant enzymes. CuONS treatment resulted in an imbalance in pro-apoptotic Bax and anti-apoptotic B-cell lymphoma2 (Bcl2) levels. Histologically, CuONS induced glomerulus degeneration and vacuolation in tubules lining epithelium. Immunohistochemical evaluations revealed strong expressions of nuclear factor kappa-light-chain-enhancer of activated B cells (NF-kB), tumor necrosis factor-alfa (TNF-α), and the tumor suppressor gene (p53) in CuONS-treated kidneys. Ultrastructural assessments further confirmed these structural abnormalities. While CuONS exhibits potential as a nanopesticide, caution is warranted due to observed negative impacts on kidney functions, and histological architecture, in this study. Careful consideration of potential side effects on other living organisms is imperative in the utilization of CuONS in agricultural practices.
