Much faster directed evolution of proteins could speed development of molecular machine systems

Phage-assisted continuous evolution of proteins is roughly a hundred times faster than conventional laboratory evolution of proteins, perhaps speeding the development of components for molecular machine systems.

Combined computational and experimental study illuminates motions of molecules across a surface

Combined computational and experimental study shows molecules walking, hopping and flying across a surface; may lead to controlling molecular motion.

Nanotechnology boosts anticancer drug cocktail many times over

Porous silica nanoparticles covered with a lipid bilayer deliver large doses of drugs and kill cancer cells a million fold better than do simple liposomes.

DNA nanotechnology builds 3D forms with complex curves (includes video)

The capabilities of scaffolded DNA origami procedures have been expanded to construct arbitrary, two- and three-dimensional shapes.

Real-time monitoring of atomic force microscope probes

Real-time monitoring of atomic-force-microscope probes to adjust for wear may speed up and improve the accuracy of measurements and manipulations done with AFMs.

High-resolution structure reveals versatility of RNA nanotechnology

A high-resolution crystal structure of a small square made by self-assembly of RNA molecules reveals each corner of the square to have a unique structure.

Nanotechnology promises low-cost method to squash superbugs

Novel biodegradable nanoparticles destroy membranes of drug-resistant ‘superbugs’ without harming blood cell membranes.

Confining enzymes in specially engineered nanoporous materials may advance nanotechnology

Engineering both the pore size and chemical functionality of nanoporous materials affects both the secondary structure and the catalytic activity of the enzymes confined in the nanopores.

Toxicity of silver nanoparticles on Arctic soil

Research showing a toxic effect of silver nanoparticles on nitrogen-fixing bacteria in Arctic soil demonstrates the need for more research on nanoparticle environment, health, and safety.

Nanotechnology makes possible boat 40% stronger and 75% lighter than metal boats

Zyvex Technologies announced that its 54-foot boat named Piranha completed a rough-weather sea test near Puget Sound in the Pacific Ocean, demonstrating record fuel efficiency.
