Zusammenfassung:In article number 2003725, Xiangjia Li, Yang Chai, Yong Chen, and co‐workers present limpet tooth inspired painless microneedles with the capability of controllable drug delivery. The microneedles are fabricated via a magnetic field‐assisted 3D printing process, and the aligned magnetic nanoparticles show promising enhanced compression resistance. This opens intriguing perspectives for designing microneedles with sharp features and excellent mechanical strength based on bioinspired hierarchical structures.
