Abstract

This paper introduces highly programmable microscale swimmers driven by the Marangoni effect, capable of self-propelling on water surfaces without external stimuli. A photopatterning method enabled the high-throughput generation of microswimmers with multiple functional parts and distinct material properties. The researchers programmed various motions, including time-dependent direction changes and swimmer disassembly, without external energy sources.
