Tubular Microstructures Via Controlled Nanoparticle Assembly

There is an increasing interest in using nanoparticles as building blocks for well-defined structures that have practical applications owing to the various novel properties of nanoparticles. However, their assembly is a challenging task. Methods based on surface functionalization, andor template patterning have been used for this purpose, but both of these processes can be rather complicated. Thus, there is a continuing need for a simple method for synthesizing high aspect ratio microstructures constituted of nanoparticle building blocks.
