In the present work, we investigated the morphological and wetting properties of 
chitosan-based films exposed to a pulsed UV laser presenting a fluence inferior to the 
ablation threshold for such samples. Recent experiments reported that the immobilization of 
dansyl derivatives on chitosan films may be used to produce fluorescent polymeric films with 
properties required by many electro-optical applications. By using the sessile drop method, 
we found that the immobilization of a dansyl group on the chitosan backbone affects the UV 
stability of the resultant polymeric system. The dynamic contact angle measurements were 
analyzed in the context of the molecular-kinetic theory, which allowed to estimate the 
surface density of adsorption sites involved in the wetting phenomena, as well as the 
surface contribution to the wetting free energy. The present work thus brings additional 
information regarding the mechanism behind the photodegradation of dansyl-chitosan films that 
can potentially be used in many sensor devices.
