About this collection

Associate Editor for Journal of Material Chemistry B and Materials Advances, Elizabeth Cosgriff-Hernandez (The University of Texas at Austin, USA) introduces this Editor’s Choice collection on scaffold engineering:

“The truly exciting aspect of tissue engineering is that it harnesses the body’s ability to heal itself. The paradigm shift to working with the body provides numerous opportunities to learn from nature and improve upon current therapeutic strategies. Tissue engineering requires coordination of a multifaceted design that both restores function and guides regeneration. One of the challenges is synthesizing biomaterial scaffolds with appropriate degradation profiles while maintaining appropriate mechanical properties and cell-material interactions. In addition to synthesis of new biomaterials with unique properties, there is also a critical need to advance biomaterial fabrication strategies to achieve greater complexity and function.

In the current collection, I have selected outstanding papers published during recent years in Journal of Materials Chemistry B and Materials Advances that highlight advances in scaffold engineering and biomaterial design for tissue engineering applications. These articles provide exciting results that span multiple fabrications strategies, including hydrogel design and cell carriers, advanced electrospinning of fiber scaffolds, and engineering complex architectures with composites and 3D printing.”
