Medium-resolution force volume (FV) (64 × 64) compressed morphology (a) and corrected morphology (b), using sharp pyramidal probe, for hydrogel-1 filled with Al2O3 nanoaggregates in 5% weight concentration. Young’s modulus map (c) using 20 nN indentation force in 1:1 correspondence with the morphology. Scanning electron microscopy (SEM) imaging of the same freeze-dried sample (d). White circles show nanoparticle aggregates inside hydrogel surface.
