Synthesis and Characterization of Hierarchical Mesoporous-Macroporous TiO2-ZrO2 Nanocomposite Scaffolds for Cancellous Bone Tissue Engineering Applications

Scanning electron microscopy (SEM) images of (a) sample S26Zr, (b) sample S50Zr, (c) sample S76Zr, and (d) sample S86Zr which are completely inappropriate for cells to attach and grow in. It seems that the different amount of zirconia and titania has made heterogeneity in their structure which results in forming cracks and weak pores and pore walls and also the high amount of zirconia in the samples has a detrimental role in structural integrity.
