A new generation of cancer treatments based on nanotechnology is making its way out of the laboratory and into the clinic with the promise of targeting cancer cells while steering clear of healthy tissue.
Research from North Carolina State University demonstrates that a relatively new microscopy technique can be used to improve our understanding of human tissues and other biomedical materials. The study focused specifically on eye tissues, which are damaged by scarring in diabetic patients.
A research team at Case Western Reserve University has found that gold catalysts shaped in the form of a cube, triangle, or other higher order structures grow nanowires about twice as fast and twice as long compared to wires grown with the more typical spherically-shaped catalysts.
An international research team led by scientists at Lawrence Berkeley National Laboratory and SLAC National Accelerator Laboratory has used a powerful X-ray laser to shine new light on a tiny cluster of molecules that is integral to an important stage of photosynthesis known as Photosystem II.
U.S. researchers are perfecting simulations that show a nuclear weapon's performance in precise molecular detail, tools that are becoming critical for national defense because international treaties forbid the detonation of nuclear test weapons.
The new technique considers the density of monochromatic elements as 'nanoposts' that are arranged in one of 17 possible patterns or 'shades'. It then produces faithful reproductions of grayscale images using these 17 shades in hand.
A new model describes the properties of optic nanoantennas at distances inferior to the nanometre by means of quantum mechanics, an advancement which completes the explanations based on classic physics equations which have been applied until now.
Wieder sorgen Wuerzburger Physiker fuer neue Erkenntnisse in der Spintronik: In extrem duennen topologischen Isolatoren haben sie spin-polarisierte Stroeme nachgewiesen, welche die Theorie seit sechs Jahren vorhersagt. Zugleich zeigen sie einen Weg der Anwendung fuer neuartige Rechner.
As the field of nanomedicine matures, an emerging point of contention has been what shape nanoparticles should be to deliver their drug or DNA payloads most effectively. A pair of new papers by scientists at The Methodist Hospital Research Institute (TMHRI) and six other institutions suggests these microscopic workhorses ought to be disc-shaped, not spherical or rod-shaped, when targeting cancers at or near blood vessels.
It would make life a lot easier if the surfaces of window panes, corrosion coatings or microfluidic systems in medical labs could keep themselves free of water and other liquids. A new simulation program can now work out just how such surfaces have to look for a variety of applications.
