Back Cover: Article 2200272 by Xin Yang, Pengyu Lv, and their co-workers, demonstrates that hydrophobic polymer entanglements can function as robust crosslinking points to prepare anti-swelling hydrogels with high stiffness. The hydrogels have cartilage-equivalent compressive modulus and strength and are nontoxic to the cell. Moreover, the hydrogels can be processed into various complex shapes by direct ink printing, promising for articular cartilage replacement.

具有高刚度的物理缠结抗膨胀水凝胶

封底：Xin Yang、Pengyu Lv 和他们的同事的文章 2200272 证明疏水性聚合物缠结可以作为坚固的交联点来制备具有高刚度的抗溶胀水凝胶。水凝胶具有与软骨相当的压缩模量和强度，对细胞无毒。此外，水凝胶可以通过直接墨水打印加工成各种复杂的形状，有望用于关节软骨置换。
