Nanoelements with unique properties are produced by many colloidal particle synthesis methods, but there are still challenges in implementing micro and nanoelements onto surfaces to exploit their properties in practice. Flow-driven assembly is one of the most widely used bottom-up directed assembly methods to implement various types of elements into many arrangements including lines and arrays on the surface. However, this method typically takes many hours to assemble over macro-scale areas (cm²), making it unsuitable for high rate/high volume nanomanufacturing. Herein, we present an entirely new flow-driven assembly technique called interfacial convective assembly, in which colloidal particles were selectively integrated on the patterned surfaces up to two minutes. Using this method, we have assembled organic and inorganic particles such as Polystyrene Latex (PSL), silica, gold and silver. In situ experiments were performed to understand the assembly mechanism. It was demonstrated that the evaporation rate inside the feature is different than other regions. Adjusting the parameters precisely led to the assembly of nanoparticles (NPs) in complex shapes over large areas such as the world map.
