Electropolymerization of Au nanoparticle incorporated poly(dopamine) thin-films at a micro liquid|liquid interface.

ABSTRACT: Dopamine (DA) is an important biomolecule of the central nervous system (CNS) as well as a monomer incorporated into melanin, a macromolecule often associated with skin pigmentation. Herein, we have investigated the electropolymerization of DA to form polydopamine (PDA) at a micro interface between two immiscible electrolyte solutions (micro-ITIES) between water|1,2-dichloroethane (w|DCE) under external, electrochemical control. DA oxidation to form PDA was achieved via the use of an ionic liquid composed of trihexyltetradecylphosphonium (P₆₆₆₁₄) paired with AuCl₄ ^- and dissolved in the DCE phase. AuCl₄ ^- acts as a strong oxidizer, accepting electrons from DA to form Au nanoparticles (NPs) that become incorporated into the growi
