Biopolymer based films for wound dressings

University of Coimbra, Portugal
In recent years, various studies have focused on producing and improving treatments for skin regeneration. Polymers are the
most important components of these systems in terms of release characteristics and permeation of drugs as well as mechanical
properties of the formulations of these systems.The biopolymer films have become a very popular choice since they are biodegradable
and biocompatible. In our group we have developed some hydrogels based on gelatin, pectin, starch and alginate to be applied as
drug delivery systems. Here we wish to report the preparation of new wound dressings based on chitosan and dicarboxylic acids
from renewable sources. Membranes based on pectin and chitosan were also developed. The films were physically, chemically and
biologically characterized. Finally, they were loaded with polyhexanide (PHMB) which works as an antiseptic. The hydrophilic
properties were evaluated. The effects of the sterilization by gamma irradiation and by heat treatment were accessed and the effect
on the final properties of the films was evaluated.
