Toughening 3D-printed Sr–HT–Gahnite caffold through natural and synthetic polymer coating
Bone scaffold for aiding bone regeneration in large bone defects should have following ideal characteristics; biocompatibility, biodegradability, bio-activity, high porous and interconnected-pore architecture, as well as, mechanical characteristics similar to the cortical bone for supporting loads. 3D printed Sr–HT (Sr–Ca2ZnSi2O7)–gahnite scaffold with hexagonal pore structure is an interesting bone scaffold meeting most of these ideal features. To explain, biocompatible, osteoinductive, and osteoconductive properties as well as unique high compressive strength are obtained from Sr–HT–gahnite, glass-ceramic, material. With hexagonal pore structure, the scaffold has compressive strength comparable to cortical bone balancing with high porosity and large pore size. Nonetheless, the scaffold…
Hierarchical Fibrillar Scaffolds Obtained by Non-conventional Layer-By-Layer Electrostatic Self-Assembly
A new application of layer-by-layer assembly is presented, able to create nano/micro fibrils or nanocoatings inside 3D scaffolds using non-fibrillar polyelectrolytes for tissue-engineering applications. This approach shows promise for developing advanced scaffolds with controlled nano/micro environments, and nature and architectures similar to the natural extracellular matrix, leading to improved biological performance.
