*Abstract

Many nanoparticle assembly approaches such as convective assemblies, metal deposition methods (such as evaporation), and dip coatings have been used till date. However, these approaches are associated with possible limitations such as a poor selectivity, an increased temperature, and need of special vacuum systems in case of metal deposition; a long process time, and an application difficulty (especially for thin and bendable substrates) in case of dip coating; and a surface treatment requirement for convective assembly. This novel method involves an interfacial convective assembly of nanoparticles into high aspect nanostructures without using common prior art assembling requirements such as surface treatment, particle charge, electric current, and excess heat.
