Abstract

Polymer–enzyme films are prepared via sequential adsorption of an imidazolium-based poly(ionic liquid), poly(1-ethyl-3-vinylimidazolium bromide), and an enzyme, glucose oxidase. Their formation and stability toward disassembly in salt-containing aqueous media is examined by means of quartz crystal microbalance with dissipation monitoring and supported by electrochemical measurements of the enzymatic responses. A considerable fraction of the enzyme remains bound to the polymer even at high ionic strength of the surrounding solution, thus indicating remarkable stability of the polymer–enzyme films.
