In this study we report on the stability of microemulsion templated mesoporous silica materials as a function of exposure time to 0.01 M phosphate buffered saline (PBS) at pH 7.4, determined via nitrogen sorption. The sorption isotherms were seen to have retained their characteristic shape even size distributions, BET surface areas and total pore volumes, indicates that the structural integrity of the materials has largely been maintained. Preliminary analysis of the small angle x-ray scattering (SAXS) data of unexposed cell size was seen to increase as the template size increased, a trend that is seen to reflect the polydispersity present in the template as previously determined via small angle neutron scattering (SANS).
