In this paper, we report our investigation on the monolayer characteristics of a nontoxic, biocompatible, and biodegradable polymer chitosan (CHS) using Langmuir–Blodgett technique. It has been observed that pure CHS do not form stable monolayer. However, when CHS is mixed with arachidic acid (AA), stable self supporting monolayer is formed at air–water interface. This also can be transferred onto solid substrate. CHS–AA mixed monolayer is extremely stable with variation of pH. Atomic force microscopy study confirms the formation of stable uniform CHS–AA films onto solid support.

The phase behaviour and surface structure of dipalmitoyl phosphatidyl choline (DPPC) monolayers at the air/water interface, in the absence and the presence of procaine, have been investigated by Langmuir-Blodgett (LB) technique and atomic force microscopy. The LB films were transferred on mica, at a controlled surface pressure, characteristic for the expanded liquid to condensed liquid phase transition of pure DPPC monolayers. The results indicate that procaine penetrates into and specifically interacts with phospholipid monolayers stabilizing the lipid membrane interface.
