Color in living organisms can be formed two ways: pigmentation or anatomical structure. Structural colors arise from the physical interaction of light with biological nanostructures. A wide range of organisms possess this ability, but the biological mechanisms underlying the process have been poorly understood.
The University of Southampton's Chemistry department has been awarded a National Chemical Landmark blue plaque by the Royal Society of Chemistry, to celebrate the 40th anniversary of the discovery of a technique that has revolutionised science.
University of Akron researchers have developed new materials that function on a nanoscale, which could lead to the creation of lighter laptops, slimmer televisions and crisper smartphone visual displays.
A team of physicists has succeeded in performing an extraordinary experiment: They demonstrated how magnetism that generally manifests itself by a force between two magnetized objects acts within a single molecule. This discovery is of high significance to fundamental research and provides scientists with a new tool to better understand magnetism as an elementary phenomenon of physics.
Seine Methode ist ungewöhnlich und hat Potenzial: Mit Laserlicht möchte Dr. Philipp Wagener von der Universität Duisburg-Essen hochreine Nanomaterialien erzeugen, um die Katalyse und die Energietechnik effizienter zu machen.
Using gold nanoparticles, MIT researchers have devised a new way to turn blood clotting on and off. The particles, which are controlled by infrared laser light, could help doctors control blood clotting in patients undergoing surgery, or promote wound healing.
Just months after setting a record for detecting the smallest single virus in solution, researchers at the Polytechnic Institute of New York University announced a new breakthrough: A nano-enhanced version of their biosensor detected a single cancer marker protein and even smaller molecules below the mass of all known markers. This achievement sets a new benchmark for the most sensitive limit of detection, and may significantly advance early disease diagnostics.
A new biosensor, applied to the human skin like a temporary tattoo, can alert marathoners, competitive bikers and other 'extreme' athletes that they're about to 'hit the wall', scientists are reporting.
Artists and craftsmen more than 2,000 years ago developed thin-film coating technology unrivaled even by today's standards for producing DVDs, solar cells, electronic devices and other products. Understanding these sophisticated metal-plating techniques from ancient times could help preserve priceless artistic and other treasures from the past.
Researchers from the National Institute of Standards and Technology (NIST) and the University of North Carolina have demonstrated a new design for an instrument, an 'instrumented nanoscale indenter', that makes sensitive measurements of the mechanical properties of thin films - ranging from auto body coatings to microelectronic devices - and biomaterials.
