Front Cover : In article number 2000238 by Anthi Ranella, Maria Farsari, and co‐workers, multiphoton lithography is employed for the fabrication of 3D cell scaffolds with negative Poisson's ratio. It is shown that even though the photoresist SZ2080, is stiff, the scaffolds are elastic and cells penetrate them and proliferate in them, adapting the scaffold shape to suit their requirements. This work paves the way for the fabrication of metamaterials 4D scaffolds for tissue engineering.

用于组织工程应用的激光制造3D辅助超材料支架

封面：Anthi Ranella，Maria Farsari及其同事的文章编号2000238中，采用多光子光刻技术制造了具有负泊松比的3D细胞支架。结果表明，即使光致抗蚀剂SZ2080坚硬，支架仍然具有弹性，并且细胞可以穿透它们并在其中扩散，从而适应支架的形状以适应其要求。这项工作为用于组织工程的超材料4D支架的制造铺平了道路。
