Polyelectrolyte Membrane with Hydroxyapatite and Silver Nanoparticles as a Material for Modern Wound Dressings

Abstract

Modern wound dressings not only play a covering role but also facilitate the function of the wound, contributing to a faster healing process. In this paper, we present a polyelectrolyte system with nanosized elements that could stimulate the growth of eukaryotic cells while providing antimicrobial properties, which may be recommended as a potential dressing material. The proposed platform consisted of polyethyleneimine, hydroxyapatite, and silver nanoparticles and was characterized using various macroscopic techniques. The constructed membrane scaffold was evaluated with immobilized WEHI 164 cells as a model system for cells sustained at the interface of bone and skin. Moreover, the bacteriostatic function of the designed membrane material was evaluated using different bacterial strains.
