摘要: A novel flow-guided assembly approach is presented to accurately align and position nanowire arrays in pre-defined locations with high throughput large-scale manufacturing capability. In this approach, a polymer solution first filled an array of microfluidic channels. Then gas flow introduced blow out most the while pushing little leftover against channel wall for into nanowires. way, highly ordered nanowires are conveniently aligned direction patterned along both sides microchannels. study, we demonstrated process by producing millimetre-long across 5 × 12 mm area same orientation basic 'I-shape', 'T-shape', 'cross' patterns. The assembled were further converted conductive carbon through standard carbonization process. After being integrated electronic sensors, sensitivity was found model protein sensing tests. This new anticipated open doors fabrication nanowire-based systems serve as good practice its simplicity, low cost, alignment reliability, throughput.
