Funding Secured for Diamondoid Mechanosynthesis Research Wednesday, Aug 13 2008

Finally, some serious research will experimentally explore the possibility of diamondoid mechanosynthesis (DMS). This research will be conducted in the UK. Here’s the first paragraph of the press release:
Professor Philip Moriarty of the Nanoscience Group in the School of Physics at the University of Nottingham (U.K.) has been awarded a five-year £1.53M ($3M) grant by the U.K. Engineering and Physical Sciences Research Council (EPSRC) to perform a series of laboratory experiments designed to investigate the possibility of diamond mechanosynthesis (DMS). DMS is a proposed method for building diamond nanostructures, atom by atom, using the techniques of scanning probe microscopy under ultra-high vacuum conditions. Moriarty’s project, titled “Digital Matter? Towards Mechanised Mechanosynthesis,” was funded under the Leadership Fellowship program of EPSRC. Moriarty’s experiments begin in October 2008.
If reliable DMS is possible, it could eventually lead to full-fledged molecular nanotechnology, which would have diverse applications, many of them dangerous. Advocates of MNT traditionally overestimate the probability of MNT being possible at all while underestimating the negative applications of the technology.
I’ve been following the Foresight Institute, the leading molecular nanotechnology-oriented non-profit, for many years now. Looking back, I feel disappointed at the lack of emphasis on the dangers of MNT in the organization’s message and online material. I call on the Foresight Institute to focus more on the potential downsides of molecular nanotechnology. (Note: the Foresight Institute’s President, Christine Peterson, has indicated in the comments that there is indeed be a new policy focus on the topic of addressing potential downsides, through an initiative called Open Source Physical Security. She spoke about this at the 2007 Singularity Summit.)
Back to the research at hand. Here’s a summary of what’s been happening. For the last few years, Rob Freitas and Ralph Merkle have been putting together a minimal toolset for DMS. The press release describes this as a “comprehensive three-year project to computationally analyze a complete set of DMS reaction sequences and an associated minimal set of tooltips that could be used to build basic diamond and graphene (e.g., carbon nanotube) structures.” Now, Philip Moriarty, along with one postdoc and four PhD students, will experimentally test many of the predictions presented by this study.
This research will have huge ramifications for the future of manufacturing and medical technology, whether it succeeds or not. Many of the most interesting cybernetics technologies would require atomically precise manufacturing to be implemented successfully. It’s uncertain how we might get atomically precise manufacturing, but DMS is one possible route. Synthetic biology is another. If this research reveals that DMS is harder than the advocates think, then synthetic biology may start receiving more attention as a general-purpose manufacturing approach.

I’m no nanotech scientist. But wouldn’t one need to get beyond the use of just carbon in order for nanotech devices to sense and have body movement? If so, having mastered DMS, how difficult would it be to synthesize using other types of atoms?

I am a diamond nanotech scientist! Carbon (being in the same group of the periodic table as silicon) exhibits interesting electrical properties and so could be used to sense body movement. Diamond devices in particular have advantages in the body due to their high resistance to wear, better mechanical properties and biocompatibilty. You have a point though. Dopant atoms such as boron are currently being used to enhance the semiconducting properties of diamond, and to realise some devices these atoms may be needed; however, at the nanoscale carbon’s desirable electrical properties are in their element (no pun intended). For example, graphene (single sheet diamond/graphite) and carbon nanotubes demonstrate record breaking charge mobilities and other unforeseen electrical phenomenon (fixed carrier speed, etc.)
Clever manipulation of carbon at the nanoscale will potentially lead to multifunctional devices that will usher in the predicted ‘Diamond Age’. I will be following this project with keen interest.

Michael writes “I call on the Foresight Institute to focus more on the potential downsides of molecular nanotechnology.”
Foresight’s new policy focus, Open Source Physical Security, is an approach to addressing such potential downsides. See the keynote video and slides on the OSCON 2008 website.
We invite everyone to attend the Convergence conference, Nov. 15-16, 2008 at the Computer History Museum in Mountain View, Calif, to explore this proposal. Conference website coming shortly.
Best wishes,
Christine

Christine, fantastic. I liked your talk at the Singularity Summit, and can’t wait to see more work on that theme.

“Professor Moriarty”? Bet he gets a kick, or just gets kicked around, from that.
More seriously, this is encouraging news.
