Extended dimer placement tool
for diamond mechanosynthesis. This image is a detail from
"Extended dimer placement tool for diamond mechanosynthesis"
and is described as "Extended
dimer placement tool having larger handle structure."
This geometric image is not only functional, it is an exquisite design
of the molecular structure.
More recently, to answer those who remain skeptical of the entire MNT enterprise, including the possibility of medical nanorobotics, Robert Freitas has turned his attention to figuring out how to build the nanorobots – the issue of implementation of the long-term vision.

recently, to answer those who remain skeptical of the entire MNT
enterprise, including the possibility of medical nanorobotics, I’ve
turned my attention to figuring out how to build the nanorobots – the
issue of implementation of the long-term vision. I’m now involved in 6
research collaborations with various university and corporate groups in
the U.S, U.K. and Russia in an effort to push forward the technology in
this area as fast as possible. These collaborations include a variety
of computational chemistry simulations of plausible mechanosynthetic
tooltips and reaction sequences, coupled with a nascent experimental
effort that is just starting up. Earlier this year  I also filed
U.S. patent on diamond mechanosynthesis
that describes a specific process for achieving molecularly precise
diamond structures in a practical way."
-- Robert A. Freitas, Jr.
A. Freitas Jr., J.D., has degrees in
physics, psychology, and law, and has written nearly 100 technical
papers, book chapters, or popular articles on a diverse set of
scientific, engineering, and legal topics. He co-edited the
NASA feasibility analysis of self-replicating space factories
and in 1996 authored the first detailed technical
design study of a medical nanorobot
ever published in a peer-reviewed mainstream biomedical journal. Most

first book-length technical discussion of the potential medical
applications of molecular nanotechnology and medical nanorobotics,

“The most important applications of machine-phase nanotechnology will be in medicine. Not only will human health, comfort, safety, and pleasure be vastly improved, but nanomedicine could dramatically extend the lifespan of the individual human being and greatly expand the possibilities of the human form. I’m trying to help lay the technical foundations for the future field of medical nanorobotics by conducting theoretical analyses of specific nanomedical systems and by writing a 4-volume technical book series that looks at all relevant issues including basic engineering capabilities, biocompatibility, systems and operations of medical nanorobots, clinical applications, and ethical issues.”
I undertook the Nanomedicine book series in an attempt to establish a solid foundation for the single most important future application of MNT. The book introduces a long-term vision for nanorobotic medicine and articulates the technical underpinnings of that vision, so that when the day arrives that we have the technology to build such devices, we’ll have a clearer idea what can be done with them, and how.
Ralph Merkle and I are also writing an entire book-length discussion of diamond mechanosynthesis, entitled Diamond Surfaces and Diamond Mechanosynthesis (DSDM), to be published in 2006 or 2007. The first half of this book is an extensive review of all that is presently known about diamond surfaces, and has been mostly written for several years. The second half describes specific tools and reaction pathways for building those surfaces using positionally controlled mechanosynthetic tools, and methods for building those tools.
Once diamond mechanosynthesis and the fabrication of nanoparts becomes feasible, we will also need a massively parallel molecular manufacturing capability in order to assemble nanorobots cheaply, precisely, and in vast quantities. Kinematic Self-Replicating Machines (KSRM) (Landes Bioscience, 2004, and freely available online), co-authored with Ralph Merkle, surveys all known current work in the field of self-replication and replicative manufacturing, including all known concepts of molecular assemblers and nanofactories. It is intended as a general introduction to the systems-level analysis of self-replicative manufacturing machinery. With 200+ illustrations and 3200+ literature references, KSRM describes all proposed and experimentally realized self-replicating systems that were publicly disclosed as of 2004, ranging from nanoscale to macroscale systems. The book extensively describes the historical development of the field. It presents for the first time a detailed 137-dimensional map of the entire kinematic replicator design space to assist future engineering efforts. It includes a primer on the mathematics of self-replication, and has an extensive discussion of safety issues and implementation issues related to molecular assemblers and nanofactories. KSRM has been cited in two articles appearing in Nature this year (Zykov et al, Nature 435, 163 (12 May 2005) and Griffith et al, Nature 437, 636 (29 September 2005)) and appears well on its way to becoming the classic reference in this field.
