Wires, rods, tubes, and other related 1D structures show great technological potential as (bio)sensors, catalysts, optoelectronics, etc . This can be explained by the preferential exposure of low-energy crystal facets, long segments of flat crystal planes, and fewer defects . In addition, these 1D materials have anisotropic structure, which them with a quantum confinement effect, efficient electron transport, and optical excitations .
