A nanotech formulation may have saved one of the most promising broad-spectrum antiangiogenesis cancer therapies from being side-tracked due to neurotoxic side effects.
A novel nanotech procedure produces metal nanostructures containing uniform hexagonal pores about 10 nm across that could supply new catalysts, faster metal wires for microchips, and better optical materials.
Antibody-coated carbon nanotubes only bind to cancer cells targeted by the antibody, and irradiation with near-infrared light causes the bound carbon nanotubes to heat up and kill the cancer cells.
A major nanotech advance in engineering multifunctional nanoparticles for imaging and therapeutic applications combines a short RNA (siRNA) to “silence” a specific gene with quantum dots and a “proton sponge” polymer coating to get the siRNA into the cell and released into the right compartment of the cell.
Millimeter-scale nanotech structures self-assembled from hybrid nanowires can sense and respond to external stimuli.
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.
