In this work, the reactivity of low-molecular-weight chitosan with a hydroxyl radical was evaluated. An enhancement of the antioxidant properties of chitosan in the presence of silver ions has been shown. It has been determined that under the action of irradiation on the chitosan-silver system, silver nanoparticles are formed, the size of which can be controlled by the type of action on the system.
