Abstract :

Developing bottom-up nanofabrication technologies to enable the manipulation of well-defined structures at the nanoscale level is an intense field of research. Here, the discussion is not meant to be an exhaustive review of self-assembly techniques, but rather a focused point on some aspects of this concept that I considered and applied to a particular nano-object, a single wall carbon nanotube, for nanoelectronics purposes.  

First, I will discuss a chemical self-assembly route and its use for the realisation of nanotube-based electronic devices. Then, a DNA-directed approach will be presented. Indeed, self-assembly based on molecular recognition can provide a versatile technique for the site-controlled implementation of nano-components in predefined positions and configurations. In this context, the properties that make DNA so successful in acting as a genetic material also make it a suitable candidate for constructing new materials on the nanometre scale. Because of its unique recognition properties, its size and the sub-nanometric resolution, DNA is of particular interest for positioning and organizing nanomaterials: DNA can be engineered to both create scaffolds or circuits, and attach to other materials in order to include those materials in the self-assembly process.

To conclude I will present some routes and perspectives for future work.
