Utilizing inverse micelles to synthesize calcium phosphate nanoparticles as nano-carriers
Source abstract
Abstract
The aim of this study was to investigate the feasibility of the inverse micelles (IM) technique in producing protein-loaded calcium phosphate nanoparticles (CaP NPs), and to compare this technique with the conventional co-precipitation (co-ppt) technique. In this study, bovine serum albumin and lysozyme were used as model proteins. The results show that CaP NPs produced by IM were shown to be spherical and homogenous in size of ~50 nm. Protein loading efficiency of the IM technique was shown to be much higher than CaP NPs synthesized through co-ppt technique. X-ray photoelectron spectroscopy shows that proteins were not adsorbed onto the surface of IM-synthesized CaP NPs, which suggested that the proteins were entrapped within the particle matrix. Release studies show that protein release was more rapid at lower pH conditions (pH 5 and 6) than at physiological pH of 7.4. A burst release was observed for co-ppt CaP NPs, while a continuous release of protein was observed for IM-produced CaP NPs. This study shows the superiority of the IM technique in preparing pH responsive CaP NPs as nano-carriers.
