Peptoid technology for molecular nanosystems — My review is now online

November 7, 2011

My invited review “Peptoids at the 7th Summit: Toward Macromolecular Systems Engineering” [pdf] kicks off the peptoid special issue of Biopolymers: Peptide Science.
Astoundingly, all the papers are open access.
Here’s the abstract:

Peptoids at the 7th Summit: Toward Macromolecular Systems Engineering
Methods for facile synthesis of extraordinarily diverse peptide-like oligomers have placed peptoids at the center of [...]

Nanosystems for India

May 6, 2011

Wiley India publishes textbooks “catering to the needs of Indian students”, and now offers Nanosystems:  Molecular Machinery, Manufacturing, and Computation, the book I wrote on the principles and potential components, architectures, and implementation pathways for high-throughput atomically precise manufacturing systems.
Here’s a list of Indian distributors.
Wiley India, a branch of John Wiley & Sons, the original [...]

New project launched:
Atomic Scale and Single Molecule
Logic Gate Technologies

November 25, 2010

The Atomic Scale and Single Molecule Logic Gate Technologies project is a Singapore/EU effort that aims to build atomically precise digital devices and circuits by direct surface manipulation at cryogenic temperatures.
According to the project leader, Prof Christian Joachim, “The UHV interconnection machine at IMRE [in Singapore] is the only one in the entire project that [...]

The Molecular Machine Path
to Molecular Manufacturing (2):
Exploiting Improved Methods and Building Blocks

December 27, 2009

Part 4 of a series on the history and prospects of advanced nanotechnology concepts, prompted by the upcoming 50th anniversary of Feynman’s historic talk, “There’s Plenty of Room at the Bottom”.

Rigid, structurally diverse bis-peptide oligomers C. Schafmeister, JACS, 2006

In this post, I’d like to outline the promise of fabrication technologies that are within reach of [...]

How to make carbon nanotubes
at room temperature

November 15, 2009

As I noted in a recent post on self-assembled nanoelectronics (“Carbon Nanotube Transistors through DNA Origami”), carbon nanotubes (CNTs) hold promise for self-assembled nanomechanical systems, too: They are orders of magnitude stiffer than biomolecules, and can serve not only as rigid components, but also as low-friction linear and rotary bearings to support moving parts.
Recent [...]

My MIT dissertation — a draft of Nanosystems —
is now online

September 26, 2009

My MIT doctoral dissertation, “Molecular Machinery and Manufacturing with Applications to Computation”, is a draft of Nanosystems: Molecular Machinery, Manufacturing, and Computation, and MIT has now made it available as a 30 MB pdf. You can download it here.
The Nanosystems project began as notes for a seminar that I taught at Stanford, grew toward a [...]

A Third Revolution in DNA Nanotechnology

May 22, 2009

In a new paper, Shawn Douglas and his colleagues at William Shih’s lab have demonstrated the first systematic method for building multilayer 3D nanostructures of DNA. In his commentary, Tom LaBean calls this “a third revolution in DNA nanotechnology”, following Seeman’s launch of the field and Rothemund’s development of the breakthrough origami technique.
In the authors’ [...]

Slides for Berkeley Talk
on Molecular Nanosystems

May 6, 2009

Framework-directed self assembly
I’ve now posted the slides for my Berkeley talk on objectives and experimental directions in biomolecular/inorganic composite nanosystems: Click here to download.
The talk was a keynote at the 2009 Berkeley Nanotechnology Forum.
I’ve described some of the concepts and motivations in an earlier post, and this technology direction is also discussed in the report [...]

Macromolecular Modeling
for Molecular Systems Engineering

April 16, 2009

Nir London of the Macromolecular Modeling Blog has invited me to offer my perspective on the field. After patiently waiting for me to complete it, he’s posted the resulting essay, which I have cross-posted below.
The Macromolecular Modeling Blog is hosted by the Rosetta Design Group, which offers molecular modeling services based on the Rosetta protein [...]

Nanosystems for Molecular Manufacturing

April 4, 2009

While upgrading parts of the E-drexler.com website, though, I’ve been re-reading some of the on-line content from Nanosystems: Molecular Machinery, Manufacturing, and Computation, the book that grew into, then out of, my MIT dissertation. Nanosystems explores what physics tells us about the potential of advanced molecular manufacturing systems and products. It outlines some ideas about [...]

Polyoxometalate Nanostructures

March 29, 2009

My technical talks often include a slide that shows several kinds of atomically precise components that may prove useful in composite nanosystems. One image is labeled “polyoxometalates”, a name that isn’t widely known. I think it should be.
Polyoxometalates (POMs) are molecular structures that are, in effect, atomically precise bits of metal oxide that contain [...]

Low-Cost DNA Production Roadmap

December 21, 2008

Synthetic DNA today costs millions of dollars per kilogram, but Harvard‘s George Church has proposed an approach that could drop the cost by many orders of magnitude. This could greatly expand applications of structural DNA nanotechnology.
