Features of the Influence of UFS/Raffinose Nanocomposites on In Vitro Cultivation of Gametes of Swine

摘要

Modern nanotechnologies are intensively used in various fields of science and technique, including biotechnology, agriculture, and medicine. A new trend in the realm of the synthesis of nanoparticles is the biological synthesis using polymer matrices, which are nontoxic and can be easily synthesized in any form that is necessary for a certain way of use. Similar matrices include biopolymers such as starch, chitosan, cyclodextrin, and ultrafine silica (UFS), which are acting as a stabilizer and recovering agent. The use of biopolymers in the production of nanoparticles has several advantages over conventional synthetic reagents. The high molecular weight chains of such biopolymers are characterized by a large number of hydroxyl groups, and therefore such structures can form complexes with target molecules. This ensures control of the size, shape, and dispersion of nanoparticles, which makes them less toxic to mammalian cells [5, 7]. UFS possesses a unique complex of physicochemical, medical, and biological properties: high sorption capacity for proteins, toxins, lack of allergenic and harmful effects on cells, and activation of reparative processes [2, 6, 10].
