Fabrication of Gold Microwires by Drying Gold Nanorods Suspensions

The ramification pattern of gold nanorods is fabricated by drying its suspension between two glass slides. The aspect ratio of the nanorods and the pinning on the contact line among air, water, and substrate are important. After being baked, this pattern also conducts electricity. The method of patterning is useful for microwiring without the additional need to pattern the wires into specific shapes.
