Bioactivity and Drug Delivering Ability of a Chitosan/46S6 Melted Bioactive Glass Biocomposite Scaffold

The form of the prepared scaffold is shown in FIG. As evidenced by mercury porosimetry, it can be observed that all of the prepared stents have a wide range of interconnected pores, including macroscopic, microporous, and nanoporous. By increasing the MB concentration the pore size in the scaffold also increases. By increasing the concentration of MB from 0% by weight to 66.5% by weight, the average pore size of the prepared stents increased from 150 ± 5 μm to 170 ± 24 μm. All scaffolds prepared with different MB concentrations have a wide range of pore sizes indicating that the pores in all the scaffolds are interconnected and the seed cells diffuse throughout the scaffold.

Scientists have found some success in combining bioactive glass nanoparticles with chitosan to develop synthetic bone grafts. Bioactive glass is a glass ceramic biomaterial that successfully binds physiological structures such as bone. Bone cells grew relatively rapidly and were found to be covered with grafts of bioactive glass and chitosan. Further research is necessary. Researchers say they need to pay more attention to improve the dispersion of nanofillers in the chitosan matrix. The tremendous opportunities provided by these materials, and their unbelievable possibilities for nanotechnology, are expected to revolutionize biomedical fields in the near future.

The chitosan derivative and the water-soluble chitosanase product have different structural and physicochemical properties which can lead to new discoveries of new biological activities or known biologically active compounds.

Chitosan is a naturally abundant aminated polysaccharide. Its chemical properties give chitosan unique functional properties. The main feature of chitosan is its degree of acetylation and molecular weight. These are decisive for the functional properties of chitosan, from solubility and material forming ability of chitosan to biodegradability and various bioactive properties. The great potential to use chitosan in various fields has long been recognized. The biological properties of chitosan makes it particularly suitable for applications related to agriculture, food and environmental engineering applications. In this chapter we will explore the relationship between the chemical properties of chitosan and its main functional properties.
