Novel beeswax-chitosan/Zinc-hydroxyapatite biocomposite porous scaffolds: Preparation and biological evaluation

Abstract

We developed a novel BW-CS/ZnHA biocomposite utilizing Beeswax-Chitosan and Zinc-hydroxyapatite nanoparticles (ZnHAP). The uniformed mixture of beeswax-chitosan and ZnHAP was freeze-dried to get a porous biocomposite. The fabricated biocomposite was characterized using FTIR, XRD, and SEM. Moreover, the antibacterial, swelling, biodegradations, viability, and cell proliferation capacity of the fabricated biocomposite was assessed. The biocomposite demonstrated upgraded swelling and antibacterial activity. The addition of ZnHAP accomplished the antibacterial activity. Biocompatibility studies were carried out using osteoblast cells and thus we proved the non-toxic nature of the biocomposite. Osteoblast cell adhesion investigations demonstrated that the cells were appended and infiltrated into the inside of the biocomposite. The obtained results encourage the use of these bandages for various types of wounds with infection and exudates.
