One unsettling prediction Del Montes made is that terrorists could get their hands on nanoweapons as early as the late 2020s through black market sources. History of nanotechnology. [12][13] C60 was not initially described as nanotechnology; the term was used regarding subsequent work with related carbon nanotubes (sometimes called graphene tubes or Bucky tubes) which suggested potential applications for nanoscale electronics and devices. Dual polarisation interferometry is one tool suitable for characterisation of self assembled thin films. Perhaps they would haven't been motivated to carry out their senseless act if more news stories covered how the theoretical grey goo resulting from nanobots devouring the world around them was a concept that had long been abandoned by the originator of the idea. Nanobots are the real concern about wiping out humanity because they can be weapons of mass destruction, said Louis Del Monte, a Minnesota-based physicist and futurist. Dr. Andrew Maynard, chief science advisor to the Woodrow Wilson Center's Project on Emerging Nanotechnologies, concludes that there is insufficient funding for human health and safety research, and as a result there is currently limited understanding of the human health and safety risks associated with nanotechnology. These seek to create smaller devices by using larger ones to direct their assembly. These "nanotechnology 35mm telephoto zoom monoculars" are only collecting 25x more light than the unaided eye sees under the best conditions. Scientists currently debate the future implications of nanotechnology.
