This research work was planned to test biosafety of different nanomaterials on the different animals models. These nanoparticles were previously used as potential insecticides of mosquito larvae. The biosafety of these nanoproducts were evaluated on certain organs of non target animals that associated with mosquito breeding sites in Egypt. Animal organs such as the kidneys of rats, toads, and the fish's spleen were used as models to study the biological toxicity of these nanomaterials. After 30 days of the animals receiving the nanomaterials in their water supply, different cell mediated immune cells were assessed in these tissues. Both TNF-α and BAX immuno-expression were also used as immunohistochemical markers. Histopathology was conducted to detect the effect of the tested nanoproducts at the tissue level of the liver and kidneys of both the rats and toads. Green nanoemulsion of the lavender essential oil was relatively more effective, safe, and biodegradable to be used as insecticides against mosquito larvae than the metal-based nanomaterials.
本研究旨在测试不同纳米材料对不同动物模型的生物安全性。这些纳米颗粒先前曾被用作潜在的蚊虫幼虫杀虫剂。这些纳米产品的生物安全性在与埃及蚊虫滋生地有关的非目标动物的某些器官上进行了评估。动物器官,如大鼠、蟾蜍的肾脏和鱼类的脾脏,被用作研究这些纳米材料生物毒性的模型。在动物通过饮水摄入纳米材料 30 天后,对这些组织中的不同细胞介导免疫细胞进行了评估。TNF-α 和 BAX 免疫表达也被用作免疫组织化学标志物。组织病理学用于检测在大鼠和蟾蜍的肝脏和肾脏组织水平上测试的纳米产品的效果。薰衣草精油的绿色纳米乳液比基于金属的纳米材料更有效、安全和可生物降解,可作为杀虫剂来防治蚊虫幼虫。
