Layer-by-layer deposition of avidin and polymers on a solid surface to prepare thin films: significant effects of molecular geometry of the polymers on the deposition behaviour

Abstract

An alternate and repeated deposition of avidin and biotin-labelled polymers (polyethyleneimine or polyamidoamine dendrimer) provides the avidin–polymer thin films on a solid surface, in which the loading of avidin in each layer depends significantly upon the molecular geometry of the polymers.
