The Mechanism of the Initial Stage of Synthesis of Polydopamine

Based on the analysis of the regularities of the interaction of dopamine borates and dimethyl silyl ether, two alternative mechanisms of their oxidation for the purpose of obtaining polydopamine as a promising product for the creation of new and efficient adhesive compounds for joining biological tissues are proposed. An explanation of the presence of a threshold concentration of dopamine in the reaction system which provides the formation of polydopamine is proposed.
