One-dimensional (1D) nanostructures have unique electronic, optical and mechanical properties that have attracted intense interest over the past two decades. Single wall carbon nanotubes (SWNTs) and semiconducting nanorods, in particular, have long been recognized as potential candidates for future nanoelectronic applications. DNA nanostructures offer biofunctionality and are presently being explored for use as scaffolds and transport agents for both biological and inorganic nanospecies. Thus far, it has proven exceedingly challenging to take full advantage of the properties of these nanostructures. Their small size and the fact that their synthesis occurs either at high temperatures or in solution make it difficult to organize them in complex architectures, a key requirement for their exploitation. As a step toward this goal, we are developing an approach leading to the controlled and ordered arrangement of nanoobjects on lithographically patterned, chemically (or biochemically) functionalized surfaces. The basic requirements for this approach are: molecular-scale lithographic patterning; control over nanostructure length; and facile end-functional chemistry. We believe this may be a viable avenue toward building well controlled, robust nanoelectronic devices and circuits.

Brief Bio:

Erika Penzo received her Bachelor of Science and Master of Science degrees in Physics Engineering from Politecnico di Milano in 2005 and 2008, respectively. She spent 8 months while pursuing her master's degree at the Massachusetts Institute of Technology as a visiting student with Prof. Francesco Stellacci, in the Material Science Department. There, she investigated synthesis and characterization of organic coated metal nanoparticles. Ms. Penzo is currently a Ph.D. candidate at Columbia University in the Applied Physics Department. The focus of her research is the directed molecular-scale assembly of functional nanostructures with a goal of creating future generation electronic circuits.
