Influence of the surface pressure on the organization of mixed Langmuir-Blodgett films of octadecylamine and butyrylcholinesterase. 2. Film transferred onto silica support

摘要

We investigate here the structure of mixed octadecylamine/butyrylcholinestase Langmuir-Blodgett films which have already been studied at the air-water interface (part 1). FTIR-ATR and AFM techniques were used to characterize mixed enzymatic LB films transferred onto silanized Ge and oxidized silicon supports, respectively. The structures of the films at 30 and 40 mN m(-1) surface pressures are proposed, and a very well-structured film is obtained at 40 mN m(-1). [References: 13]
