Abstract

original image

Zero-dimensional nanoparticle structures have a prominent role as building blocks for complex assemblies. However, major barriers to the construction of 1D assemblies using 0D elements exist. The fabrication of free-standing all-nanoparticles thin fibers is presented, where the fibers have a uniform diameter (1.5 µm) and a high aspect ratio (length/diameter ≥ 2500).
