Surfactant presence in a multilayer polyelectrolyte-enzyme system improves its catalytic response
Self-assembling of poly(allylamine) containing an osmium polypyridil complex (PAOs) alternatively with sodium dodecyl sulfate (SDS) and glucose oxidase (GOx) generates a ternary multilayer system, (PAOs/SDS/PAOs/GOx)n. The introduction of this anionic surfactant allows a sensitive increase of the po...
