The ability to create an ensemble of nanostructures with specific size, shape, and arrangement on particular positions in space is one the most fundamentally important issues in the exploration nanoscience and realization nanotechnology. Self-organization of objects has been exploited to form an ensemble of certain nanostructures by ‘luck’. From the point of view realizing the dream of nanotechnology, i.e., to be able to manipulate materials on the atomic scale, we still have a very long way to go.

The concept of ‘constrained self-organization’, which means to impose a set of constraining rules on a self-organization process in order to select a small desired subgroup from numerous possible outcomes of the process, appears to be an attractive option for realizing the dream of nanotechnology. The constrained growth of nanochannel arrays with desired geometry will be presented as examples to illustrate the concept[1-4]. The potential exploitation of the concept of constraining the self-organization of atoms and molecules on solid surfaces will also be discussed[5-9].
