Preparation of Microcrystalline chitosan (MCCh)/tricalcium phosphate complex with Hydroxyapatite in sponge and fibre form for hard tissue regeneration. This work present chitosan and a new method to obtain derivatives such as MCCh/ß-TCP complex with nano and micro size of calcium phosphates in different forms (sponge, fibres), including chemical characterization, mechanical properties, particle size, morphology, solution stability, biodegradation, bioactivity and also a new method to obtain nanoceramic formation in chitosan salt solution. These materials can be used in the future for medical applications as a base for scaffold production, as implants in regenerative medicine.
