- •
The model explaining interaction between chitosan and DMPA is also valid for DPPC and DPPG monolayers.
- •
Low molecular weight chitosans interact more strongly with DPPC and DPPG monolayers.
- •
Penetration into the hydrophobic chains was confirmed with PM-IRRAS and SFG data.
- •
Chitosan-rich and lipid-rich condensed domains are formed with chitosan incorporation.
- •
Rh for LMWChi is smaller than for Chi which explains its easier access to hydrophobic tails.
