ABSTRACT
Doctors are concerned that nanoparticles are so small that they could easily cross the blood-brain barrier—a membrane that protects the brain from harmful chemicals in the bloodstream. Eric Drexler, the man who gave nanotechnology its name, taught people about "green goo" and "grey goo" of self-replicating machines. He also wrote about the human desire and how they manipulate technologies to meet their needs. The fictional grey goo nanobots that are a result of molecular manufacturing gone wrong will bring about a real concern with molecular manufacturing in the next few years and the effects of crime and new ways to deal with it using crime science or early policing to detect crime using scientific ways to prevent it. The Center for Responsible Nanotechnology (CRN) is a non-profit think tank concerned with the major societal implications of advanced nanotechnology. CRN promotes public awareness and education, and the crafting of effective policy to maximize benefits and reduce dangers.
