Africa-Press – Lesotho. <\/strong><\/span>Scientists from the National University of Science and Technology (NUST MISIS) have teamed up with their colleagues from the Russian Academy of Sciences to prove the high eco-toxicity of silver nanoparticles.
\nThey have obtained evidence of these nanoparticles\u2019 eco-toxicity after experimenting with zebrafish (Danio rerio) embryos. An article summing up the results of their research project has been published in the Journal of Hazardous Materials.<\/p>\n

It is common knowledge that silver is a heavy metal, and that large amounts of it tend to intoxicate the human body. Since times immemorial, people have also known that silver acts as a decontaminant. Experts continue to study silver nanoparticles whose worldwide application in commercial goods increases steadily each year.<\/p>\n

This makes people think about their safety, with scientists assessing potential environmental consequences and risks and studying the influence of various properties of nanoparticles on various organisms.<\/p>\n

This research paper is part of an ambitious project that involves scientists who are trying to develop nanoparticle eco-toxicity models. Such models make it possible to assess the eco-toxicity levels of new nano-materials in advance.<\/p>\n

\u201cWe have studied the eco-toxic effect of two types of silver nano-particles, that is, flat and spherical nano-particles,\u201d Natalia Abramenko, who co-authored a book on this issue, told RIA Novosti.<\/p>\n

\u201cThe experiment involved four types of zebrafish (Danio rerio) embryos that were treated with two types of silver nano-particles and silver ions, and a sample survey was also conducted.
\nScientists mixed a silver nanoparticle solution consisting of water and the above-mentioned nanoparticles with the incubation medium or a saline solution for the development of spawn.<\/p>\n

Zebrafish (Danio rerio) embryos were immersed in this solution, with scientists observing their development specifics and morphological deviations on a daily basis.<\/p>\n

According to authors, both forms of silver nano-particles displayed high eco-toxicity levels, as compared to silver ions (AgNO3). At the same time, flat silver nano-particles proved to be even more toxic than spherical ones.<\/p>\n

\u201cPrevious research explained the eco-toxicity of silver nano-particles by the presence of silver ions (as a result of nano-particles\u2019 partial dissolution).<\/p>\n

Our results make it possible to say that the eco-toxicity of silver nano-particles is linked precisely with the presence of nano-particles inside samples,\u201d Abramenko said.<\/p>\n

This data expands current perceptions of the relationship between nano-particles\u2019 specifications and their eco-toxicity. According to scientists, it can be used to assess various risks of introducing nano-materials and to obtain highly safe nano-particles.<\/p>\n
