Abstract: The present invention relates porous osteoinductive nanocomposites and for the methods to prepare osteoinductive nanocomposites. The osteoinductive composites consist of biocompatible polymers and non-heated (or non-sintered), needle-shaped or plate-like calcium phosphate nanocrystals and the methods comprise the steps of: a. adding phosphate to a calcium solution thereby evoking precipitation of calcium phosphate nanocrystals; b. washing the nanocrystals with water and suspending them in an organic solvent or getting dry calcium phosphate nanocrystals after evaporating organic solvent; c.
