A Rubik’s cube as a reconfigurable microfluidic system is presented in this work. Composed of physically interlocking microfluidic blocks, the microfluidic cube enables the on-site design and configuration of custom microfluidics by twisting the faces of the cube. The reconfiguration of the microfluidics could be done by solving an ordinary Rubik’s cube with the help of Rubik’s cube algorithms and computer programs. An O-ring-aided strategy is used to enable self-sealing and the automatic alignment of the microfluidic cube blocks. Owing to the interlocking mechanics of cube blocks, the proposed microfluidic cube exhibits good reconfigurability and robustness in versatile applications and proves to be a promising candidate for the rapid deployment of microfluidic systems in resource-limited settings.

在这项工作中提出了魔方作为可重构微流体系统。微流体立方体由物理互锁的微流体块组成，通过扭曲立方体的表面，可以实现定制微流体的现场设计和配置。微流体的重新配置可以通过在魔方算法和计算机程序的帮助下求解一个普通的魔方来完成。O 形环辅助策略用于实现微流体立方体块的自密封和自动对齐。由于立方体块的互锁机制，所提出的微流体立方体在多功能应用中表现出良好的可重构性和鲁棒性，并被证明是在资源有限的环境中快速部署微流体系统的有希望的候选者。
