Polyelectrolyte complex materials consisting of antibacterial and cell-supporting layers

The characterization of a polyelectrolyte complex material comprised of two biopolymers, a

chitosan upper layer and a gellan gum under layer, is reported. It is shown that the upper layer

of chitosan with incorporated levofloxacin displays an antibacterial activity, while the under

layer of a gellan gum/TiO2 composite supports the growth

of fibroblastic cells.
