Abstract

Different production areas, such as food, agriculture and technology, demand products based on nanotechnology. This fact alerts the community to the possible effects that products composed of nanoparticles (NPs) can cause to the environment, and, consequently, to living organisms. NPs can be present in biological systems and linked to molecules that perform different functions in organisms and cells. Due to their high surface-to-volume ratio, NPs are highly reactive and catalytic, and can pass through cell membranes. However, their interactions with these systems are not well known. Despite this, some studies have warned about the possible effects of NPs, when in contact with some living organisms. In Brazil, there is no law that determines the permissible concentration of these in food, as well as the disposal of NPs in the environment. Thus, through metallomonic platforms and other omonic platforms, this project focuses on evaluating the biological effects of soybean plants, grown in the presence of silver, copper and silica nanoparticles, through macro plant characteristics, such as growth, mass humidity, germination rate, among others, as well as possible changes in terms of (metal) proteins, lipids, enzymes and metals under the influence or not of NPs.
