The article (the first one from the suggested serial) deals with the main ideas, conceptions and terms of the new and rapidly developing sphere of human cognition and practice – nanotechnology. The nanochemistry problem field is determined and it’s objects (clusters, nanoparticles, quantum dots) are briefly characterized as well as their very special properties. Nanochemistry is a new area of modern science. In the field of education the training courses considering interdisciplinary character of given area of a science are now developed. Key words: chemical education, nanotechnology, nanochemistry, nanoparticles.
