What do atoms look like? Can we actually see them? Why does a gecko stick to the ceiling? What about nano particles in medicine? Why does the Lotus plant always stay clean? Nanotechnology offers a great diversity in many different subjects: medicine, technology, biology, chemistry and the electronic sector. We want to find out more about new materials, about the tools and techniques used and about the advantages of nanotechnology in everyday life. We are also going to have a closer look in health and environmental concerns and carry out several experiments to reveal the secret of such small but powerful matter.
