RGD was grafted on HA particle surface by carbodiimide method to increase the cell recognizing function of HA particles,and then the particles were homogenously distributed in PLLA to prepare porous composite.HA particles and porous composite were characterized by XPS and SEM.The results show that RGD was successfully grafted on HA particle surface,RGD-HA particles were nano-size and homogenously distributed in the porous composite.Cell adhesive ratio of RGD-HA/PLLA porous composite increased from 37.21% of ordinary PLLA/HA to 69.11%.
