Light-powered microrobotic swarms, excelling in manipulation efficiency and motion pattern customization, are pivotal for micro-fabrication and biomedical applications. Herein, we introduce an integrated platform capable of autonomously transporting light-powered microrobotic swarms over long distances within complex environments. The embedded real-time feedback control algorithm ensures swarm integrity and facilitates the adept navigation around unpredictable obstacles. The successful operation of both trapping- and nudging-based microrobots prove the versatile applicability of our platform.
Precise rotation of biological cells plays a pivotal role in in-situ bio-imaging and bioengineering. Here, we propose an integrated platform that enables the rotation of various ellipsoidal cells along their major and minor axes via tailoring the laser patterns and corresponding optothermal fields. Label-free in-situ three-dimensional(3D) imaging of living cells is achieved by 3D reconstruction.
