Abstract :
Dielectric barrier discharge plasma treatment has been found to significantly improve hydrophilicity of the surfaces of interconnected porous calcium hydroxyapatite (IP-CHA), particularly that of wall surfaces of the internal pores. IP-CHA has been clinically used as a material for bone substitutes in bone tissue regeneration. Higher hydrophilicity of IP-CHA obtained in this method is expected to further increase the osteoconductivity of IP-CHA.
