Large-Scale Patterning and Assembly of Carbon Nanotubes by Microfluidic Hydrodynamic Focusing

Abstract:

Efficient integration of synthetic nanotubes/nanowires into functional nanodevices by bottom-up approaches is the key of mass production of nanodevices, and is still a big challenge. Here we present a simple microfluidic method of patterning and aligning a large scale of carbon nanotubes by hydrodynamic focusing: the sample solution carrying carbon nanotubes were hydrodynamically controlled by the sheath flows. This method can be used to align and position both a large scale of nanotubes and a few lines of nanotubes to designated positions, offering a general pathway for assembly of nanosystems.
