Mixed Langmuir−Blodgett films of behenic acid and glucose
oxidase have been elaborated. The resulting
films have been studied by scanning force microscopy with the
“tapping” mode, from the micrometer scale
to the nanometer scale. The general organization of the mixed film
and the enzymatic quasi 2D crystals
have been observed. Lateral force microscopy, coupled with
topographic data obtained with the contact
mode, has made possible the distinction between enzyme and behenic acid
domains.
