The influence of silver nanoparticles on biological objects

At present nanotechnologies have gained powerful devel- opment in the world, the volume of industrial production ofnanomaterials is increasing every day, reaching several thou- sand tons per year in developed countries. Unnatural very small engineered particles are released into the environment as a result of such human activities. Nanoparticles causing an unprecedented type of industrial pollution directly affect all living organisms. Therefore, the risks caused by engineered nanomaterials both to humans and environment have to be evaluated. The purpose of the review is analyzing the world literature about the effects of one of the most widespread silver nanoparticles on living organisms of different levels of biological organization and habitats. It is shown that safety issues with engineered nanoparticles are studied using biotesting methods by the world scientific community. When studying the effect of nanoparticles on various biological ob- jects, the literature describes ambiguous results...
