Nanotechnology fabrication techniques move towards multifunctional architectures

Abstract:
Some pundits writing about nanotechnology get carried away by their own hype and talk about self-assembly as if bottom-up fabrication technologies, where molecules get assembled into everyday products, are just around the corner. We took a swing at this in our Spotlight from a few days ago (Nanotechnology 'pencil sharpeners' add to researchers' nanofabrication toolbox). Today we bring you another example from the cold reality of the labs that makes clear how early stages this whole field of self-assembly really is. Today, when researchers - with both feet firmly on the ground - talk about self-assembly they mostly talk about template-assisted nanocrystal superlattices in the form of planar thin films. Bottomline is that even the controllable fabrication of highly ordered homogeneous nanostructures on surfaces remains a difficult challenge. And IBM's much touted 'self-assembling nanotechnology' (see: IBM applies self-assembling nanotechnology to conventional chip manufacturing) is nothing more than a patterning process that creates a film with trillions of holes around the on-chip wiring. Moving from a planar geometry of self-assembled nanoscale building blocks such as nanocrystals or nanotubes to a free-standing, three-dimensional multifunctional architecture is not a trivial undertaking. Researchers are just about to make the first steps to such multifunctional (still nanoscale) hierarchical architectures that both retain the properties of the nanocrystals and offer multifunctionality.
