This essential gives an overview of the physical principles underlying nanotechnology, which today make it possible to use microscopic effects technologically. Methods are presented which allow the production of nanostructures with highest precision. In the last chapter the author gives an overview of exciting technological applications, starting with the use of nanotechnology-based effects in church glass windows to solar cells and CCD chips. 
This book is a translation of the original German 1st edition Licht in der Welt der Nanotechnologie by Christian Schneider, published by Springer Fachmedien Wiesbaden GmbH, part of Springer Nature in 2016. The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation. Springer Nature works continuously to further the development of tools for the production of books and on the related technologies to support the authors.
