O Livro de Código Aberto de Nanociência e Nanotecnologia
Nanotecnologia e nanociência é aproximadamente o controle e o entendimento da matéria na escala submicrométrica e atômica.
Este wikilivro sobre nanociência e nanotecnologia reúne informações sobre as várias ferramentas, métodos e sistemas para fornecer aos estudantes, pesquisadores e todos os outros em um manual e guia geral em open-source (código aberto) para este campo vasto, interdisciplinar e em expansão - sendo um livro que pode ser ajustado por colaboradores na medida que as informações neste desenvolvem-se.
- Latest major additions in: Health effects of nanoparticles, Environmental Impact, and Nanotechnology Demonstration Experiments
- Sections Nano & Society, nanooptics and electron beam lithography are in preparation.
Why is nanotechnology such a 'hot' subject - and is it more hype than substance? This part gives a brief introduction to the visions of nanotechnology and why so many people are working on it around the world. To help set a perspective there are overview tables with timelines, length scales and information resources.

Microscopes allows us to probe the structure of matter with high spatial resolution, making it possible to see for instance individual atoms with tools such as the scanning tunneling microscope, the atomic force microscope, and the transmission electron microscope. With the related spectroscopic methods, we can study the energy levels in nanosystems. This part gives an overview of the tools and methods used in microscopy and spectroscopy of nanostructures.

Combining nanodevices into functional units for real life application is a daunting task because making controlled structures with molecularly sized components requires extreme precision and control. Here we look at ways to assemble nanosystems into functional units or working devices with top-down or bottom-up approaches.
