TEM and SEM micrographs of nanoparticles. The NPs prepared at 20% drug loading and aqueous phase of 0.1% tween 80 were studied by TEM (a). The same NP formulation was freeze-dried with and without cryoprotectant and was studied by SEM: micrograph of freeze-dried NPs with 0.5% glucose (b) and SEM micrograph of freeze-dried NPs without cryoprotectant (c).
