Since Richard Feynman imagined arranging atoms one by one in 1959 to current research in nanoscience and (bio)nanotechnology, scientific progress continues to feed societal expectations. Increasingly, we read about new scientific developments in (bio)nanotechnology that could bring solutions to vexing problems in human existence. Radical extension of life expectancy, human-machine interface, and nano-devices for targeted drug delivery represent only few examples of the potential applications of nanotechnology. These emerging technologies have tremendous applications and could enhance the quality of life of many people. However, they also raise important social, ethical and legal/regulatory questions. With the pressure to pursue scientific progress in order to find solutions to pressing human problems, the dangers of unreflectively developing (bio)nanotechnology lurks around the corner.
