Microbots Swimming in the Flowing Streams of Microfluidic Channels.

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 micropartides into desired locations is achieved. The m...

Sumario: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 micropartides into desired locations is achieved. The microbots are powerful enough to propel them- selves 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.
