The NATO ARW "Molecular Self-Organization in Micro-, Nano-, and Macro- Dimensions: From Molecules to Water, to Nanoparticles, DNA and Proteins" to commemorate Professor Alexander S. Davydov was held in Kiev, Ukraine, on 8-12 June, 2008, at the Bogolyubov Institute for Theoretical Physics of the National Academy of Sciences of Ukraine. Theobjective ofthisNATOARWistounveilandformulatetheprincipalfeatures that govern myriads of the molecular self-organization processes in micro-, nano-, and macro-dimensions from the following key representatives such as liquid - ter and aqueous solutions, and molecular liquids, nanodots, nanoparticles including gold, solitons, biomolecules such as DNA and proteins, biopolymers and bios- sors, catalysis, molecular modeling, molecular devices, and thin ?lms, and to offer another, more advanced directions in computational, experimental, and technolo- cal areas of nano- and bioscience towards engineering novel and powerful molecular self-organized assemblies with tailored properties. Nanoscience is indeed one of the most important research and development fr- tiers in modern science. Simplistically, nanoscience is the science of small particles of materials of a size of nanometre. Molecular nanoscience and nanotechnology have brought to us the unprecedented experimental control of the structure of matter with novel extraordinary properties that open new horizons and new opportunities, and new ways to make things, particularly in our everyday life, to heal our bodies, and to care of the environment. Unfortunately, they have also brought unwelcome advances in weaponry and opened yet more ways to foul up the world on an en- mous scale.
