Welcome to the new world of science We pass from the micro world of the 20th century to the nanoworld of the 21st We discover how by forgetting the traditional fabrication of objects from blocks of raw material the idea of assembling objects atombyatom came about We will approach the ultimate logic of nanotechnologies whereby any object can theoretically be assembled from atoms

In this episode learn how nanotechnologies could fundamentally change our vision of the world In the late 20th century computer technology revolutionized work leisure and industry Now in the 21st century our understanding of the phenomena at the very heart of matter allows us to contemplate materials with new properties copied directly from nature

Join the quest to find out what changes nanoparticles can make in our bodies as we discover new nanomedical treatments On this scale doctors can pinpoint diseased zones in the body and theyre already considering how to target affected areas and convey necessary medications in the correct doses

After the history and exploration of fantastic nano horizons we must work to understand the territory into which these discoveries applications and their resulting risks lead us Rightly and wrongly working on the scale of the invisible crystallizes many fears What are the real risks to individuals and the environment How can we evaluate them How can they be measured
