Question: “Is it reasonable to call for a regulation that prohibits further research on nanotechnology?”
Not from the point of view of DaNa and the NanoCare Cluster. There are indeed still some knowledge gaps, but that is this way with every new area of research. These gaps will be closed by the new findings from the numerous national, European and international projects. In our opinion there are so many positive aspects to nanotechnology (i.e. in the medical sector or in the protection of the environment.) that a moratorium would be contra productive.
As many processes in nature take place on the nanoscale, research on nanotechnology will lead to a better understanding of these natural processes. Advances in medicine would be very difficult if research on nanotechnology was not allowed any more. Of course the intended goals of every single project have to be validated. Ethically dubious projects are rejected by most scientists and all sponsors.
For the nanotechnologists their science is just like any other: what matters are the people working in this field and what they make of it.
