Exposure to two different wavelengths of light can cause the azobenzene molecule to switch back and forth between two different shapes. This molecular shape-changing works well in solution but until now has not worked with molecules attached to surfaces. Now scientists from Penn State University and Rice University have found a way to make the… Continue reading Tethered molecular switches as step toward actuators for nanotechnology
Atoms or molecules could be pumped through the spinning inner CNT to form patterns of atoms or molecules—a nanotech inkjet printer.
Will nanotechnology culminate with diamondoid nanorobots produced in nanofactories by atomically precise mechanosynthesis, or with “soft” machines that mimic the way biological molecular machines work?
Taiwanese researchers have constructed a molecule in which exposure to light causes causes the molecule to change shape so that rotation of one part of the molecule with respect to another part can no longer occur.
Chinese scientists have recently built an atomically precise structure directed by bonds between gold atoms—a crown of 36 gold atoms coordinating surrounding organic molecules.
Arizona State University chemists have demonstrated a nanotech version of molecular self-regulation by designing a molecule that mimics the way in which plants defend themselves from an overload of sunshine.
Sunday, May 18th at 7:00 PM Pacific / 10:00 PM Eastern, FastForward Radio will feature a distinguished panel discussing the Technology Roadmap for Productive Nanosystems. The panel will discuss the background and history of the roadmap, and explore how it will serve to help realize these horizons. The panelists are: Christine Peterson, Acting President of… Continue reading Panel to discuss productive nanosystems Sunday night
Can online gamers add to the nanotech toolkit for perfecting the de novo design of proteins that do not exist in nature?
A special issue of the International Journal of Nanomanufacturing presenting topics on manufacturing in 3D at the nanoscale (derived from the 4th International Symposium on Nanomanufacturing held at MIT in November 2006) contains a report of a nanomanipulator for the complex assembly of nanoparticles. Although the press release from Inderscience Publishers, via AAAS EurekAlert (“Are… Continue reading Will a "'proto-prototype' for a nanoassembler" lead to atomically precise manufacturing?
A new building block for structural DNA nanotechnology uses a 3-carbon glycerol molecule instead of the 5-carbon sugar deoxyribose found in DNA.
