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
A nanotech version of the optical tweezers traditionally used to manipulate micrometer-scale objects manipulates objects at the 200-nm scale.
A new concept for a very cheap plastic nanotech memory has been developed by combining the favorable properties of ferroelectrics and semiconductors.
The flagellum clutch mechanism may provide ideas useful for nanotech control of molecular motors.
Carbon nanotubes with the proper imperfections were found to replace more problematic and expensive materials in dye-sensitized solar cells.
The combination of electrical stimulation and a nanotech surface composed of carbon nanotubes dispersed in polycarbonate urethane was found to attract cartilage-forming cells.
Chemists have designed molecules that act like nanotech sensing robots by signaling information about their chemical environment.
Two different types of nanostructures have been reported as nanotech methods to clean up oil spills and other organic pollutants.
Atoms or molecules could be pumped through the spinning inner CNT to form patterns of atoms or molecules—a nanotech inkjet printer.
MIT scientists are discovering what controls the proper movement of nanoparticles into cells—the right kinds of molecules must be arranged in the right patterns.
