Artificial microswarms with a collective intelligence that can execute cooperative tasks will serve as intelligent micro/nanorobot systems for many biomedical and microengineering applications. However, it remains challenging to construct microswarms with 3D dynamic and reconfigurable structures that can execute complex spatiotemporal‐dependent tasks. Here, simply using a tapered optical fiber (TOF)...
Opto‐Hydrodynamic‐Driven 3D Dynamic Microswarms
In article number 2300480, Xing Li, Yang Shi, Hongbao Xin, and co‐workers present a convenient opto‐hydrodynamic strategy for 3D dynamic microswarm petals actuation based on the photothermal gradient‐induced Marangoni effect. Such microswarm petals are controllably reconfigurable, deformable, and capable of performing stable migration. Importantly, this...
