Abstract
Porous calcium phosphate nanospheres were successfully fabricated by a simple sonochemical method and used as a drug carrier of ibuprofen Morphology structure ibuprofen storage capacity and release rate of the calcium phosphate nanospheres were characterized using FESEM TEM Nitrogen adsorption XRD FTIR and UV–vis adsorption spectroscopies Results showed the obtained calcium phosphate nanospheres held a porous structure with an average diameter of 489 ± 1742 nm Moreover the porous nanospheres possessed an adjustable load amount and release rate for ibuprofen by changing drug concentrations during the drug loading process In addition the effects of size and dispersancy of porous spheres on drug release rate were discussed which was found that larger or agglomerate porous spheres could delay drug release process This study indicated that porous calcium phosphate nanospheres were a perfect drug carrier for ibuprofen which has potential application for the therapy of skeletal diseaseThis study is financially supported by the Program for New Century Excellent Talents in University NCET070763 Special Programm of National Natural Science Foundation of China Grant21041003 and Zhejiang Natural Science Foundation of China Y4090416
