As the story notes, this has been 10 years in progress. Here's a post on
the subject to sci.nanotech 9 years ago:

Click on the "Complete Thread" link to see John Sidle's interesting
response. Also note that the original research was on NMR, while the
breakthrough seems now to be in ESR. My post in the above thread also
indicates some of the limitations of NMR for 3-D reconstruction (not to
mention the much smaller signal involved from NMR).

And here's a query I put in on the subject of ESR and NMR about a month
prior to that:

I never did get around to trying my approach, which I now think was flawed
in conception. It was somewhat similar to Manassen's approach. I still do
have copies (somewhere!) of some of the papers Manassen published on his
ESR work back then. Plus a paper that disputed Manassen's results. I'll
have to see if I can locate them now and review them - out of curiosity.
