Macroscopic nanoparticle ribbons and fabrics

Nanoparticle (NP) ribbons and fabrics are fabricated using a facile, evaporation-driven approach that directs NP assembly at a liquid meniscus, which is constrained using principles of elastocapillarity with uniform molecular dimensions over large lateral distances. This results in the creation of uniform NP ribbons of nanoscale height and sub-micrometer width, without structural defects, across large, macroscopic areas (i.e., several square centimeters).
