Recent interview touches on new Foresight programs and issues in nanotechnology development
A set of rationally engineered transcriptional regulators for yeast will make it easier to build complex molecular machine systems in yeast, some of which may become useful additions to pathway technologies for atomically precise manufacturing and productive nanosystems.
Functioning DNA nanorobots to deliver specific molecular signals to cells were designed by combining DNA origami, DNA aptamers, and DNA logic gates.
A talk at TEDxBerkeley includes nanotechnology among the options for digital fabrication, one of five new rules of innovation.
New computational methods to explore the rapidly expanding collection of high resolution three-dimensional RNA structures reveal new RNA structural motifs, identifying additional building blocks for complex RNA nanostructures.
A set of machine learning programs can now predict properties of small organic molecules as accurately as can calculations based upon the Schrödinger equation, but in milliseconds rather than hours.
Researchers in Australia and the US have demonstrated a working transistor by placing of single atom of phosphorous with atomic precision between gates made of wires only a few phosphorous atoms wide. This demonstration points to possibly extending current computer technology to the atomic scale.
Scientists at Kyoto University and the University of Oxford have combined DNA origami and DNA motors to take another step toward programmed artificial molecular assembly lines.
Foldit game players have again out-performed scientists in protein design, this time improving the design of a protein designed from scratch to catalyze Diels-Alder cycloadditions.
Human life after advanced nanotechnology has been developed will be fundamentally different from life up until that point.
An array of 96 iron atoms on a copper nitride surface, assembled using an STM and used to write a byte, demonstrates how small magnetic storage could shrink and may lead to novel nanomaterials for quantum computers.
An article in The Guardian quotes Christine Peterson and Robert Freitas on the vision of molecular manufacturing. Freitas is quoted as expecting that the development of nanofactories could be done in 20 years for “on the order of” one billion dollars.
A four-step unidirectional molecular motor driven by light and temperature changes catalyzes different chemical reactions at different steps of its rotary cycle.
A tutorial review available after free registration presents a theory-based exploration of the difficulty in moving from simple molecular switches to arrays of artificial molecular machines capable to doing substantial, useful external work.
RNA CAD tools developed for RNA-regulated control of gene expression in synthetic biology successfully engineered metabolic pathways in bacteria. Will engineering RNA-based genetic control systems lead to design tools for other RNA-based molecular machine systems?
Protein-like structures called peptoids can be formed into stable, free-floating nanosheets.
When can we expect advanced nanomachinery to be commercialized? Will any technologies not be affected in some way by advanced nanotechnology?
A tutorial review addresses the distinction between the many simple artificial molecular devices that are currently available and truly effective artificial molecular machines that would mimic the ubiquitous molecular machines present in living systems.
In a lecture at Oxford Eric Drexler argued that atomically precise manufacturing will be the next great revolution in the material basis of civilization, and discussed how we can establish reliable knowledge about key aspects of such technologies.
