be controlled by compressing the film. Based on preliminary experimental observations, it has been suggested that tobacco mosaic virus tubules could serve as
templates for the growth of 1D lattice of quantum dots [108].

Two-Dimensional Arrays
Ligands based on long chain thiols or phosphines have served as good candidates
for assembling monodisperse nanocrystals on a flat substrate. Two-dimensional
organizations of a variety of nanocrystals can be brought about by simply evaporating a drop of the sol on a flat substrate.
