hitosan is a de-acetylated derivative of chitin, a naturally abundant polysaccharide, which is found in the exoskeleton of
crustaceans and insects and in fungi cell walls. Application of chitosan in tissue engineering and regenerative medicine
has a great potential due to its excellent biocompatibility, biodegradability and antimicrobial activity. Nano-diamonds were
firstly produced by detonation technique, and they have good biocompatibility and mechanical properties. Nano-diamonds
could be incorporated in chitosan to enhance its mechanical properties for use in bone tissue engineering. Carboxyl groups,
appearing on the surface of nano-diamonds during the synthesis and purification processes, provide an effective ionic binding
with chitosan amino groups. Properties of chitosan/nano-diamond solutions and films prepared using solution casting method
depend on the individual features of the components and uniformity of the nanoparticles distribution. The purpose of this
study is to find the relationship between the rheological properties of the chitosan/nano-diamond solutions in different acids,
the way of nano-diamond incorporation to the solution and the mechanical properties, morphology, and structure of the
composite films.
