Release profiles of BSA protein adsorption on apatite (Ap)-coated citric acid–stabilized cobalt ferrite (CFCA) (CFCA-Ap) particles. The cumulative percent of BSA released versus incubation time for the BSA-loaded CFCA-Ap particles for three pH values (4.0, 6.5, and 7.4) of phosphate buffer saline. The data points are expressed as mean ± SD; n = 3.
