From the teapot effect to tap-triggered self-wetting: a 3D self-driving sieve for whole blood filtration by Yuang Li, Xue Li, Lina Zhang, Xiaofeng Luan, Jiahong Jiang, Lingqian Zhang, Mingxiao Li, Jinghui Wang, Jiangang Duan, Haiping Zhao, Yang Zhao, Chengjun Huang

“…Abstract Achieving passive microparticle filtration with micropore membranes is challenging due to the capillary pinning effect of the membranes. Inspired by the teapot effect that occurs when liquid (tea) is poured from a teapot spout, we proposed a tap-triggered self-wetting strategy and utilized the method with a 3D sieve to filter rare cells. …”
