New composites of polyaniline and polysaccharides with applications as biomaterials: one review

Abstract

In this revision we will show some results involving composites made with polyaniline and polysaccharides and their properties as promising biomaterials. Studies about the biomedical application of conducting polymers have being considered due the electric stimulation, decrease citotoxicity, good biocompatibility, and others. Polyaniline and polymers derived from the aniline has received attention in the last years by chemical stability in environmental conditions, processibility, facility of polymerization and doping, short cost and particular properties. The botryospheran is an exopolysaccharide (EPS) classified in the group of the beta-(1 -3) glucans, produced by the fungus botryosphaeria sp.. EPS has being investigated in parallel about the variability of biological answers of defense. The potential of interaction between conducting polymers with biological environment has been considered, once the application possibilities like development of artificial muscles, nerves regeneration stimulation and medicines delivery control.
