http://scipeople.ru/publication/118623/; Toxicity of Gold Nanoparticles for Plants in Experimental Aquatic System S. A. Ostroumov, V. A. Poklonov, S. V. Kotelevtsev, and S. N. Orlov Department of Biology, Moscow State University, Moscow, Russia email: ostroumov@mail.bio.msu.ru Received April 10, 2013 Abstract: Increased production and use of nanomaterials can lead to new types of pollution of the environment, including aquatic ecosystems. Pollution of the aqueous environment with nanoparticles can be a new type of pollution of the environment. This requires a more detailed study of the biological effects during exposure of nanoparticles on aquatic organisms. The interactions of gold nanoparticles (Au) with aquatic macrophytes Ceratophyllum demersum have been studied. Aquatic microcosms with these plants were used. Gold nanoparticles (Au) were added to the aqueous medium of C. demersum macrophyte containing microcosms. The state of the plants was then analyzed. Phytotoxicity of Au nanoparticles for aquatic macrophytes was shown for the first time. A new method of phytotoxicity detection was suggested and successfully approved. Phytotoxicity at a concentration of Au (in the form of nanoparticles) of 6 . 10–6 M–1.8 . 10–5 M was shown. Original Russian Text © S.A. Ostroumov, V.A. Poklonov, S.V. Kotelevtsev, S.N.

The paper deals with the negative aspects of nanotechnology devel-opment on the global and national scales. Possible economic, envi-ronmental and social risks and latent threats to the formation of na-noindustry and nanoproducts consumption are discussed. The con-clusion about the need of intensive studies of this complex problem and development of regulatory mechanisms, legal frameworks and institutions of nanotechnology progress monitoring is made.

Ostroumov S.A., Kotelevtsev S.V. Toxicology of nanomaterials and environment. - Ecologica. 2011, vol. 18, issue 61, pp. 3-10. Manufactured nanoparticles demonstrated a variety of biological activities, including toxicity. The goal of this review articles is to summarize some evidence of a variety of toxic effects produced by manufactured nanoparticles, including both the data from literature and the new data of the authors (e.g., [42]). The toxicity of nanomaterials was shown both to prokaryotic and eukaryotic organisms. As for eukaryotic organisms, toxicity was found in bioassays with both animal and plant test systems. In further studies, it is necessary to continue the studies of various aspects of toxicity of nanoparticles, and to extend the range of organisms and test systems that are being used for assessing the biological effects of nanomaterials. The methods that were previously developed to study phytotoxicity of chemicals [15-28, 48] will be useful to generate new data on toxicology of nanomaterials.

Nano-science and technology has emerged as a frontier area of research today and hence a demand to prepare the nano-materials for the variety of application has been increased significantly to a laboratory as well as industrial level. Therefore, to fill-up these demands a synthesis technique is developed by Prof. K.C. Patil of Indian Institute of Science, Bangalore, which allows production of nano-materials on a wide scale. The technique named solution combustion synthesis (SCS) although having all the advantage of Self-propagating High temperature Synthesis (SHS); it is rather simple, economical and fast technique. The article presents brief details of technique to get started with SCS.

В работе построены математические модели поверхностей смачивания и проведены исследования особенностей и закономерностей формирования кривизн наноповерхностей различных геометрий при фильтрации тонкой очистки, а также исследовано влияние порожденных этими кривизнами эффектов на протекание контактно-гидродинамических и физико-химических процессов в современном машиностроении. Выполнены компьютерные модельные построения поверхностей смачивания, просчитаны их кривизны, определены поверхностные энергии. Рассмотрены модели контактно-гидродинамических эффектов, возникающих в силу кривизн наноповерхностей различных геометрий. // Mathematical models of wetting surface are built and peculiarities of different geometries nanosurface curvature formation fine purification are studied. The influence of effects induced by these curvatures on contact-hydrodynamic and physical-chemical processes at modern machine building also are investigated.

Affiliation: Faculty of Biology, M.V. Lomonosov Moscow State University, Moscow 119991, and Institute of Geochemistry, Moscow, Russia. It was discovered that the aquatic plant (macrophyte) Ceratophyllum demersum immobilized gold (Au) nanoparticles after their addition to water. It is the first time it was shown. The method that was used to detect and measure the conctntrations of gold in the biomass of plants (phytomass) was NAA (neutron activation analysis). http://www.ncbi.nlm.nih.gov/pubmed/20506851; PMID: 20506851 [PubMed] Key words: nanotechnology, nanoparticles, Au, gold, biogeochemistry, biotechnology, aquatic plants, macrophyte, Ceratophyllum demersum, Immobilization, water quality, monitoring, environmental science, ecology
