Lab-in-a-drop - controlled self-assembly of nanocrystals

Abstract:
Throughout human history, technologies usually involved some kind of "top-down" approach, whether it was breaking a stone axe from a larger rock or using micro- or nanolithography to etch smaller structures from larger entities. In contrast, the self-assembly of nano-objects is an example of the principally new "bottom-up" technological approach which soon may provide novel fabrication processes and products with drastically improved properties. In particular the self-assembly of colloidal nanocrystals makes it possible to obtain structures with a high level of ordering and permit construction of patterns to be used in optoelectronics, photonics and biosensing. What makes nanocrystals so attractive to researchers is the fact that the properties essential to allow the arrangement process, including their size, shape, surface protection, stabilization and charge, can be controlled along with the electronic structure of each nanocrystal. As an example, we developed a "lab-in-a-drop" technique where a variety of nanostructures with desired properties may be produced.
