描述了自走式催化微管(微机器人)在微流控系统微通道中的运动。它们的运动受到一个小磁场的精确控制，实现了将多个球形微粒输送到所需位置。微型机器人的力量足够强大，可以推动自己对抗流动的溪流。将“智能和强大”的微型机器人集成到微芯片系统中，可以实现多种芯片实验室功能，如细胞分离和生物传感。
We describe the motion of self-propelled catalytic Ti/Fe/Pt rolled-up microtubes (microbots) in the microchannels of a microfluidics system. Their motion is precisely controlled by a small magnetic field, and the transport of multiple spherical microparticles into desired locations is achieved. The microbots are powerful enough to propel themselves against flowing streams. The integration of "smart and powerful" microbots into microchip systems can lead to multiple lab-on-a-chip functions such as separation of cells and biosensing.
