The book "Self-Organization of Molecular Systems" offers a comprehensive examination of molecular self-organization across various dimensions, from micro to macro levels. It is based on the findings of a NATO workshop held in 2008 in Kyiv and aims to illuminate the fundamental features that govern the multitude of processes involved in molecular self-organization. The topics covered range from liquids and aqueous solutions to nanoparticles and biomolecules such as DNA and proteins. The work provides not only theoretical insights but also practical applications in the fields of nanoscience and bioscience. It serves as a valuable reference for researchers and students engaged with the latest developments in molecular nanoscience and technology.
