Mesopore differential plots were calculated for all scaffolds based on precise water vapor pressure and gravimetric measurements are shown in Figure . The plots revealed the volume occupied by mesopores with radii ranging from 2 -36 nm during water sorption. In general, most water sorption takes place in small pores as the volume occupied increase with decreasing pore sizes. It was found that the freezing methods or an applied SMF have little effect on water sorption mesoporosity, while the incorporation of MNPs induced a change to the mesoporosity pattern.
