The bottom–up approach is emerging as a viable alternative for low cost manufacturing of nanostructured materials. It is based on the concept of self–assembly of suitable nanostructures on a substrate. We propose various strategies to control nanostructure assembly (both organic and inorganic) at the nanoscale. Our approaches include:

(i) surface patterning through a nanostencil (i.e. a shadow mask with nanoscale features) and deposition on naturally patterned substrates, which take advantage of long–range reconstructions

(ii) we are able to control the size and luminescence properties of semiconductor nanostructures, synthesized by reactive laser ablation.

(iii) we have developed new experimental tools and comparison with simulations are presented to gain atomic scale insight into the surface processes that govern nucleation, growth and assembly.

(iv) by controlling inter-molecular interactions, we demonstrate that it is possible to create specific nanoscale patterns.

(v) we developed a simple surface modification strategy for biomaterials which enhances biocompatibility.
