Uptake and depuration of gold nanoparticles in Daphnia magna
This study presents a series of short-term studies (total duration 48 h) of uptake and depuration of engineered nanoparticles (ENP) in neonate Daphnia magna. Gold nanoparticles (Au NP) were used to study the influence of size, stabilizing agent and feeding on uptake and depuration kinetics and animal body burdens. 10 and 30 nm Au NP with different stabilizing agents [citrate (CIT) and mercaptou...
متن کاملDaphnia magna
The cellular architecture of the Daphnia compound eye visual system was studied by using computer-aided techniques. All the neurons in one half of the bilaterally symmetric optic ganglion (OG) were reconstructed in three dimensions from serial electron micrographs. The techniques employed were those developed by Levinthal and collaborators (Macagno, Levinthal, and Sobel, Ann. Rev. Biophys. Bioe...
متن کاملToxicity Assessment of Some Conventionally Manufactured Nanoparticles to Daphnia Magna
Background and purpose: Nanoparticles (NPs) are used in different industries, including electronics, pharmaceuticals, cosmetics, healthcare, and environmental processes. Therefore, it is necessary to evaluate their toxicity in the aquatic environment. Materials and methods: The acute toxicity of six different kinds of nano-sized particulates (SiO2, Fe2O3, Al2O3, TiO2, ZnO, and MgO) to Daphnia ...
متن کاملcontrol of the optical properties of nanoparticles by laser fields
در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
15 صفحه اولEvaluation of silver nanoparticles toxicity in Daphnia magna: Comparison of chemical and green biosynthetic productions
Recently nanoparticles, particularly silver nanoparticles, are broadly used in industry, hence the contamination of the environment with AgNPs has caused considerable concern. In this study, the toxicity of biosynthetic nanosilver produced by two macroalgae: Sargassum boveanum and Ulva flexuosa extracts were compared with chemical nanosilver in Daphnia magna. Size and quality of nanoparticles e...
