Welcome to the fascinating world of nanotechnology and biotechnology! What enables geckos to walk across ceilings without suction cups on their feet? How has the development of a revolutionary microscope opened the door to the nanoworld, allowing us to see from the small to the smallest? Which everyday products might contain nanoparticles? What are the secrets of our DNA, and how can it be analysed, modified or replicated? How are modern biotechnological pharmaceuticals produced and which diseases can they treat?This catalogue provides answers to these and many other fascinating questions, guiding readers through impressive highlights from the exhibition and collection at the Deutsches Museum, including PCR machines, sequencers and scanning probe microscopes. It also covers a wide range of topics that address the societal impacts of nano- and biotechnology. In-depth thematic sections offer information on the gene-editing tool CRISPR/Cas9, the labelling of nano- and biotechnological products and genetic testing at home - as well as a variety of other subjects.Our aim is to demonstrate how science and innovation can push the boundaries of possibilities. We have also addressed the potential risks of new technologies, because only when we are well and objectively informed can we form a sound personal opinion.
