Developed a one-step process to transfer silver nanoparticles of their micellar solution in isooctane to the aqueous solution of carboxymethyl chitin in the presence of antioxidants by ultrasonic irradiation, excluding an intermediate stage of producing dispersion of silver nanoparticles in water. In the macromolecular system based on carboxymethyl chitin and silver nanoparticles in the presence of antioxidants gallic acid and methyl gallate enhancement effect of silver nanoparticles stabilization has been marked. It is shown that stabilization of silver nanoparticles in carboxymethyl chitin-silver nanoparticles system in the presence of methyl gallate has been carried out most efficiently, due to various nature of substituents at carboxyl group of an antioxidant.
