3D打印新材料可与人体免疫系统兼容 有望推动人造器官移植和药物递送技术发展

Group 1 - A new type of 3D printing material has been developed by a research team from the University of Virginia, which is compatible with the human immune system and has the potential to advance organ transplantation and drug delivery technologies [1][2] - The research team modified the properties of polyethylene glycol (PEG) to create a stretchable network structure, overcoming the limitations of traditional production methods that resulted in weak and crystalline structures [1] - The innovative "foldable bottle brush" structure allows the material to be both strong and highly elastic, enabling the production of 3D printable, highly stretchable PEG-based hydrogels and solvent-free elastomers [1] Group 2 - The team indicated that by altering the shape of the UV light, complex structures can be created, opening new possibilities for manufacturing artificial organs or drug delivery systems [2] - The stretchable 3D printed PEG material has been shown to be biocompatible, suitable for in-body applications such as organ scaffolds, as confirmed by cell culture tests [2] - The material may be combined with other substances to produce 3D printed products with varying chemical compositions, showcasing its potential as a high-performance solid electrolyte in advanced battery technologies [2]
