Fabrication and characterization of hardystonite-chitosan biocomposite scaffolds

2 Hardystonite scaffolds produced by ceramization of 3-D printed preceramic filled polymer were impregnated with chitosan solutions, later neutralized into physical hydrogels. Hardystonite bioceramic and chitosan physical hydrogel were chosen for their interesting biological properties as potential bone substitutes. Five impregnation protocols, differing in impregnation vacuum, chitosan concentration, chitosan to hardystonite mass ratio and base...
