Methods of organization at nanoscale belong to the key problems that transcend different areas of nanotechnology. Self-organization phenomena can be regarded as convenient tools to obtain intricate nanoscale systems with a variety of potential functionalities, such as optical, electrical, thermal transport properties. In this presentation, I will review self-organization phenomena taking place with semiconductor nanocolloids starting with supercrystals from nearly spherical nanoparticles  and nanoparticle bioconjugates  to 1D  and 2D assemblies . Comparison of the processes in solution of CdTe and other nanocolloids reveals a number of surprising similarities with processes in proteins. The conclusion that will be reached that this is the result of fundamental analogy in the scales between proteins and nanoparticles.
