Advanced functional materials – Bioprinting Macroporous Hydrogel with Aqueous Two-Phase Emulsion-Based Bioink: In Vitro Mineralization and Differentiation Empowered by Phosphorylated Cellulose Nanofibrils
Abstract https://onlinelibrary.wiley.com/doi/full/10.1002/adfm.202400431 Aqueous two-phase emulsion (ATPE)-based bioinks, a creative innovation for bioprinting, enable the fabrication of complex 3D cell-laden hydrogels with macroporous structure, which promote cellular activities within the scaffold. However, these bioinks intrinsically lack stability and specific biofunctionality, potentially limiting their application for targeted tissue engineering. This study proposes a new perspective by introducing […]
Materials Advances – A comprehensive study on rheological properties of photocrosslinkable gallol-metal complexed hyaluronic acid-based biomaterial inks
Abstract https://pubs.rsc.org/en/Content/ArticleLanding/2024/MA/D4MA00273C This study describes the development of bioadhesive hydrogels as biomaterial inks, which combine catechol chemistry and metal coordination using gallic acid and hyaluronic acid. By controlling the phase of gelation, the properties of hydrogels can be modulated through pH and Fe3+ ion concentrations, thus allowing for diverse coordination states within the polymeric network. The […]
