What is Hydroxyapatite Mineralization on Chitosan-tragacanth Gum/silica@silver Nanocomposites and Their Antibacterial Activity Evaluation about?

The goal of this research was the fabrication of chitosan (CT)-tragacanth gum (TG)/SiO nanocomposite as a potential use in tissue engineering. For the antibacterial activity induction and stabilization of SiO nanoparticles (NPs) in the polymer matrix, SiO and green synthesized Ag NPs were hybrid with SiO/Ag. Then, the obtained hybrids were inserted into the CT-TG blend, separately. The ultrasonic waves were applied, and the films were subsequently constructed by the solution casting technique. Finally, the CT-TG/SiO nanocomposites and CT-TG/SiO@Ag nanocomposite films were studied by the variant techniques. The in-vitro bioactivity examination all samples was performed in a simulated body fluid. It was observed that hydroxyapatite was grown more on the surface of the CT-TG/SiO@Ag (1/1) nanocomposite film in comparison to the other specimens, due to its high surface area and the presence of many specific functional groups. Furthermore, the antibacterial activity assessment of the all samples were performed against Gram-negative (Escherichia coli) and Gram-positive (Staphylococcus aureus) bacteria via well diffusion method. The higher inhibition zone diameters for the CT-TG/SiO@Ag (1/
