A “cut and paste” method uses an atomic force microscope to assemble protein and DNA molecules to form arbitrarily complex patterns on a surface. Developing this approach to form enzymatic assembly lines could be a path toward a general purpose nanofactory.

An online course coupled with hands on training in Field Emission Scanning Electron Microscopy and Transmission Electron Microscopy given in Mountain View, California, is being offered by Foothill College and NASA-ASL (NASA-Ames).
Noncontact atomic force microscopy using a tip functionalized with a single molecule provides highly precise measurement of individual chemical bond lengths and bond orders (roughly, bond strength).
A combination of theoretical and experimental work on peptoids, synthetic analogs of proteins, points to the ability to design peptoids with desired structures and functions.
September 6, 2012. San Francisco. General admission to Design Night is $20 and student admission is $10. Admission fees include access to the exhibits, content such as a speaker, music, a hosted bar, and hands-on activities.
The conceptual history of nanotechnology is usually traced to a classic talk “There’s Plenty of Room at the Bottom” that Richard Feynman gave on December 29th 1959 at the annual meeting of the American Physical Society at the California Institute of Technology (Caltech), which was first published in Caltech Engineering and Science, Volume 23:5, February [...]
Studies in mice with otherwise fatal blood clots have shown that targeting a clot-busting drug to regions where blood flow is blocked restores circulation and increases survival with a much lower, safer dose of the drug.
From Desiree D. Dudley, Foresight Director of Development and Outreach: 1)Foresighters Christine Peterson and Desiree Dudley will be speaking at NASA-Ames’ Singularity University this Monday night, August 13th, from 8-10pm. Presentations are from 8-9, and a Q&A panel with H+’s Amy Li and SU’s Jose Cordiero 9-10pm! Topics will include nanotech, biotech, life-extension, and our [...]
Computational insights into a fundamental organic synthesis reaction may lead to the ability to design a catalyst for any desired reaction.
The directed, artificial evolution of genes for enzymes that produce nanoparticles of silicon dioxide and titanium dioxide produced semiconductor structures not seen in nature.
Nanotechnology combines an enzyme and a DNA molecule on the surface of gold nanoparticles to destroy hepatitis C virus in human cells and in a mouse model of disease.
Researchers have configured a 3D printer as an inexpensive, automated discovery platform for synthetic chemistry. A road to more complex molecular building blocks for nanotechnology?
A European Commission-funded video and education portal introduces nanotechnology to students and others.
A new online game allows players to design RNA molecules. The most promising designs are synthesized, and the players given real-world feedback on how well their designs worked.
The 2013 Foresight Technical Conference: Illuminating Atomic Precision will be held January 11-13, 2013 in Palo Alto, CA USA.
Nanoparticles made from specific DNA and RNA strands, homogeneous in size, composition, and surface chemistry, proved superior to other nanoparticles in silencing gene expression in tumors in mouse experiments.
A forest of long DNA strands hanging at known positions from a thin gold foil may provide a method to detect hypothetical particles of dark matter, thought to compose 26% of the universe.
A theoretical study shows that although thermal noise cannot be used to produce useful motion by mesoscale or macroscale machines, it can be used by nanoscale machines without violating the second law of thermodynamics.
The demonstration that the process of DNA replication is more flexible than thought should make it easier to incorporate unusual amino acids into designed proteins, which might make it easier to design novel protein machines.
A new nanomaterial provides a three million-fold improvement in the sensitivity of common medical tests, potentially permitting earlier detection of cancer and Alzheimer’s disease.
