[The characterization of scaffold made of N,O-carboxymethyl chitosan and tricalcium phosphate].

Purpose: To study the mechanical and chemical characterization of scaffold made of N,O-carboxymethyl chitosan (N,O-CMCS) and tricalcium phosphate(TCP) with various weight ratios.

Methods: Three composites of N,O-CMCS/TCP with weight ratios of 2:1,1:1 and 1:2 were mixed using the same volume of distilled water. The characteristic bands, morphologic structure, compressive strength and Young modulus of the composites were analyzed by infrared spectroscopy (IR),scanning electron microscopy(SEM) and universal testing machine respectively.
