Nanochemistry, describing in its simple terms, is the science of tools, technologies and methodologies for chemical synthesis, analysis and biochemical diagnostics, performed in nanolitre to femtolitre domains. It is scientific field that is concerned with generating and altering chemical systems, which develop special and often new effects as a result of the laws of the nanoworld. The bases for these are chemically active nanometric units such as supramolecules or nanocrystals. The present book is a complete information package on the topics that leads the reader into the world of application and uses of Nanochemistry.
