In the study by Giovanni Vozzi et al. on page 528 , 3D scaffolds are microfabricated by mixing poly(llactic acid) (PLLA) and multiwalled carbon nanotubes (MWCNTs) for bone tissue engineering. Their mechanical properties are measured and their biocompatibility is studied with human fetal osteoblasts (hFOB 1.19). The 3D microfabricated PLLA/MWCNT nanocomposite scaffolds show higher stiffness and cell viability than the pure 3D microfabricated PLLA scaffolds. The results suggest that biopolymer/CNT microcomposites and nanocomposites could be used as effective building blocks to replace extracellular matrices in bone tissue engineering applications. The final goal is the creation of innovative scaffolds for implants and tissue regeneration. The cover shows a light microscopy image of a 3D bone‐like pressureactivated microsyringe fabricated PLLA/MWCNT nanocomposite scaffold.
