Synthesis and applications of self-assembled nanostructures

Abstract: Self-assembled nanostructures continue to be the focus of intense research due to their obvious inspiration from Nature, and secondly, their enormous utility for patterning nanoscale structures with little outside intervention. One of the key ingredients required for future applications of nanoscale self-assembly is the ability to integrate numerous one-dimensional addressable nanostructures via their synthesis, patterning, and alignment on technologically relevant solid supports, such as semiconductor surfaces. The challenge lies in fabricating large areas of high density metallic and molecular nanostructures, with feature sizes below 50nm, in an economically feasible manner for a broad swath of applications. The foreseen applications range from computer chip design, to tissue engineering and electronic interfacing, to catalysis, to biotech, among many others. While photolithography will justifiably remain a core technology with respect to the upcoming 32nm generation in the computer industry, cost considerations for mass manufacturing, particularly with regards to lithography, remains the primary constraint for the sub-32nm era. As a result, there is very strong interest in the development of complementary patterning strategies that involve large scale self-assembly, in which a soft organic template carries out the “hard work”, spontaneously forming nanoscale assemblies in a rapid and predictable fashion. In this seminar, we will outline our approaches towards the use of self-assembled block copolymer nanostructures on technologically relevant semiconductor materials, to produce sub 50-nm features, and their applications with regards to nanomedicine and surface-based catalysis.

Note: refreshments provided; all welcome.
